Holscot supplies FEP coated seals as continuous cord on reels so your engineers can cut the exact length required on site. You can free issue your preferred core elastomer to us, including silicone, Viton®, or other specified grades, and we will apply a continuous fluoropolymer jacket in FEP, ETFE, or PFA. The finished reel gives you a clean, chemically resistant, low friction surface with a stable outside diameter and repeatable finish. This approach removes the need to hold shelves of pre-made rings and lets maintenance teams create sizes on demand with predictable quality.

We coat from 3 mm to 30 mm diameter and produce continuous lengths that run to many thousands of metres. Irregular cross sections are a speciality when a groove profile or anti-roll geometry is needed. After coating, reels are prepared for collection or scheduled call-off to suit your stocking plan.

What Holscot supplies

Holscot supplies continuous coated cord in round and non-round profiles with a uniform, defect-free fluoropolymer jacket. Standard outside diameters cover 3 mm through 30 mm, with other sizes reviewed on request. Each production run targets stable wall thickness and smooth surface finish to support consistent compression and reliable sealing. Intake of any free-issued cord is logged on arrival, processed under controlled conditions, and documented so you can maintain a clean audit trail across projects.

For projects that also require flat components, liners, or protective covers, you can round out your specification with Holscot’s fluoropolymer stock. See our fluoroplastic film and sheet range here: fluoroplastic film and sheet.

Coating choices and how we recommend them

Holscot offers three fluoropolymer coatings so you can align the jacket to your duty.

• FEP provides a very smooth, easy-clean surface with broad chemical resistance. It is the most common choice for FEP coated seals and suits hygiene focused environments and general chemical processing. 
• ETFE adds toughness where abrasion or handling wear is expected. It is often selected when cords will be routed through tighter paths or see frequent removal and refit. 
• PFA provides a higher temperature margin while maintaining near universal chemical resistance. It is a practical choice if the seal location experiences elevated process temperatures. 

Our team will help you match coating and elastomer to your media, pressure, temperature, and compression targets. If you are standardising across multiple assets, we can agree a short list of preferred combinations and lock them into your bill of materials to simplify reordering.

How the Holscot service works

1. Confirm the core
   Free issue silicone, Viton®, or another specified elastomer in continuous lengths. If you would like us to source the core on your behalf, share the target hardness, size, and duty and we will advise. 
2. Select the coating and size
   Choose FEP, ETFE, or PFA and confirm the target outside diameter between 3 mm and 30 mm. If you need a shaped cross section, provide a drawing or sample and we will confirm feasibility and recommended tolerances. 
3. Coating process
   Holscot applies a uniform fluoropolymer jacket along the full length. The process is controlled to achieve a stable outside diameter and a smooth, low energy surface that supports consistent installation. 
4. Reel preparation
   Coated cord is spooled to reel sizes that fit your stores and handling preferences. We can split a run across multiple reels for satellite sites and service kits. 
5. Collection or call-off
   Reels are prepared for collection or shipped on a call-off schedule to match shutdowns and planned maintenance. 
6. Support material
   On request we include simple cutting and joining notes so workshop teams can achieve repeatable joints in a standard jig. 

Sizes, profiles, and specials

Holscot reels cover outside diameters from 3 mm to 30 mm. Common round sizes are stocked regularly, with non-round or irregular profiles produced to order. If your design uses a keyed profile to stabilise the seal in its groove, share the profile drawing and groove details and we will confirm the recommended jacket thickness, tolerance band, and reel length for efficient cutting. Continuous runs are produced to suit your forecast usage so you can minimise changeovers and keep stores simple.

Cutting and joining on site

Creating a ring from continuous cord is straightforward with a square cut and a controlled joint.

• Cut square with a sharp blade or fine saw to maintain full face contact at the joint. 
• Use a simple alignment jig during bonding or fusion to keep the ends in plane. 
• Choose a joining method suited to your core elastomer and operating conditions. Many users select an adhesive compatible with the elastomer core. For higher pressure or temperature windows, thermal fusion or a mechanical joiner may be appropriate. 
• After cure or set, carry out a quick pressure or leak check before release to service. 

If you want to prove the method before rollout, Holscot can supply short sample lengths from the same reel so your team can practice and document the steps once.

Where customers deploy Holscot reels

Customers use Holscot reels in facilities that prefer to cut rings on demand rather than hold dozens of individual sizes. Typical placements include valve covers, pump housings, manways, access ports, inspection hatches, and light equipment enclosures. In each case the goal is the same: keep a small number of continuous reel SKUs in stores and convert them into the exact ring size at the point of work with predictable compression and clean surfaces.

Benefits for your stores and maintenance teams

• One reel covers many ring sizes, which reduces slow moving stock and simplifies reordering. 
• Consistent quality along the full length of the reel supports reliable sealing and repeatable fit. 
• The clean, chemically resistant jacket helps with washdown, wipe-downs, and duty in aggressive media while protecting the core elastomer. 
• Call-off schedules and repeatable processing align deliveries with planned maintenance windows and shutdowns. 

Quality, documentation, and traceability

Holscot maintains clear records from intake to finished reel. Each batch of free-issued cord is logged on receipt and labelled for traceability. Coating parameters are controlled for wall thickness, adhesion, and surface finish. Certificates of conformity and batch reports are available on request. Packaging is selected to protect the surface finish and keep reels clean in stores and in transit. If your internal procedures require a formal specification or drawing number, we can issue a controlled document and hold it against your account so each repeat order is produced to the same standard.

Implementation and standardisation

For sites with multiple assets, standardising on a short list of outside diameters and coatings speeds adoption and makes kit building simple. We can help you map current ring sizes to continuous cord equivalents, identify any shaped sections that benefit from an irregular profile, and propose reel lengths that balance storage space with cutting efficiency. If you operate across several locations, we can mirror reels to regional stores and maintain matching batch records for each.

Frequently asked questions

What is the typical lead time for a new size or profile
Lead times depend on diameter, coating choice, and whether the profile is round or shaped. When you share a target date at the enquiry stage, we will plan production accordingly and advise on an initial partial reel if that removes a bottleneck.

Can Holscot cut and join rings for us
The service is designed around continuous supply so your team can make any size needed at the point of work. If you want pre-cut kits for specific assets, add that to your enquiry and we will confirm what is practical.

How should reels be stored
Store reels in a clean, dry space away from sharp edges. Keep the protective wrap in place until use to preserve the surface finish.

How do we select between the three coatings
Share the media, temperature, pressure, and cleaning regime. We will recommend FEP, ETFE, or PFA based on chemical resistance, temperature margin, and handling wear.

Companion materials to complete your specification

Many projects that adopt FEP coated seals also require flat liners, wear strips, or protective covers in the same family of clean, chemically resistant materials. To keep documentation and cleaning behaviour consistent, review Holscot’s sheet and film options here: fluoroplastic film and sheet. Using related materials across seals and flat parts simplifies approval and maintenance routines.

Getting started

1. Tell us the duty including media, temperature, pressure, groove details, and any cleaning requirements. 
2. Confirm the core elastomer and supply continuous lengths for coating or ask us to propose a core. 
3. Choose FEP, ETFE, or PFA and specify the outside diameter between 3 mm and 30 mm. 
4. Agree reel lengths, collection or delivery, and any documentation you need with the shipment. 
5. If you are building a wider package, add any film or sheet requirements from Holscot’s range to complete the specification.
