REPAIR THE ENTRY SEAL
A practical fix for an
existing installation.
A conventional one-piece washer can be difficult to replace once a cable has been terminated. RetroSeal opens into two parts, so it can be fitted at the gland-to-enclosure interface.
The gland is loosened to create the fitting gap, the two washer sections are joined around the entry thread, and the gland is reassembled in accordance with the manufacturer’s instructions.
This approach can reduce the work involved in replacing a worn, damaged or missing IP washer, particularly where disconnecting wiring would make a straightforward repair more disruptive.
Reduce maintenance work
Retain a serviceable gland and reduce the dismantling, materials and labour associated with replacing a conventional washer.
Renew the entry seal
Interlocking PA6 nylon sections form a complete washer at the equipment-to-gland interface.
SELECT BY GLAND ENTRY THREAD
Find the right RetroSeal.
Match the washer to the gland’s entry thread size.
Pack quantities vary by size.
| Entry thread size | Manufacturer part code | Washers per pack | Enquire by size |
|---|---|---|---|
| M20 | RETROSEAL-M20 | 10 | Enquire about M20 |
| M25 | RETROSEAL-M25 | 10 | Enquire about M25 |
| M32 | RETROSEAL-M32 | 10 | Enquire about M32 |
| M40 | RETROSEAL-M40 | 5 | Enquire about M40 |
| M50 | RETROSEAL-M50 | 5 | Enquire about M50 |
| M63 | RETROSEAL-M63 | 5 | Enquire about M63 |
M20–M63 identifies the gland’s metric entry thread, rather than cable diameter. Ask us to confirm suitability, pricing and availability for your installation.

HOW THE TWO-PART DESIGN FITS
Retro-fit, step by step.
Installation must be carried out by qualified personnel. Follow site isolation procedures, the gland manufacturer’s instructions and all applicable requirements, including those for hazardous areas.
-
Release the gland components
Loosen the backnut and, where applicable, the middle nut to avoid twisting the cable or damaging the braid.
-
Create the fitting gap
Unscrew the gland from the enclosure by at least 5 mm. A clearance-hole entry secured by a locknut requires safe access inside the enclosure.
-
Clean the sealing faces
Clean the mating faces of the gland and equipment before fitting the replacement washer.
-
Apply the specified compound
The installation sheet calls for a small amount of electrical insulating compound on all four split ends and on the front and rear washer faces.
-
Join the washer sections
Place both halves around the entry thread and click them together. The joint is designed to assemble in one orientation.
-
Refit the gland
Secure the gland into the threaded entry or with the internal locknut, as appropriate for the enclosure.
-
Reassemble and check
Reassemble the remaining gland components to the gland manufacturer’s instructions and specified torque, then complete the required inspection.
This overview supports selection; use the full manufacturer’s instructions for the installation. RetroSeal’s IP test claim does not establish hazardous-area certification for a complete gland and enclosure assembly.

What is a RetroSeal split IP washer?
RetroSeal is a two-part PA6 nylon washer for the seal between a cable gland and an enclosure. It allows a missing, worn or damaged entry washer to be replaced around an existing gland installation.
Do I need to disconnect the cable?
The split design is intended to avoid disconnecting and re-terminating the cable. The gland still needs to be loosened and partly disassembled. Safe access inside the enclosure may also be needed, depending on the entry arrangement.
Is RetroSeal rated IP66 and IP67?
Blayds reports independent IP66/IP67 testing. Its installation sheet specifies IP66 without sealant and IPX7 with sealant. Follow the required installation method and confirm the compound for the protection level your application needs.
Which sizes and pack quantities are available?
M20, M25 and M32 are listed in packs of 10 washers. M40, M50 and M63 are listed in packs of 5. Select by the gland entry thread size, rather than the cable diameter.
Can I use it on a hazardous-area installation?
Have a qualified person assess the complete gland and equipment assembly against its certification, manufacturer’s instructions and site requirements. An IP rating alone does not confirm that an accessory is suitable for every hazardous-area installation.

Ask Cable Glands UK for RetroSeal pricingHow the estimate is calculated
- Fitting or replacement labour = glands × minutes per gland ÷ 60 × crew size × hourly labour rate.
- Washer supply = glands × washer unit price. Enter the cost of one washer, rather than one pack.
- Re-testing = glands × additional testing minutes per cable ÷ 60 × hourly labour rate, using one tester.
- Permit and isolation costs are counted once per method for the whole project.
- Production downtime = total affected project hours × downtime cost per hour. It is not multiplied by the number of glands.
- Each method's total includes labour, washers, testing, permits and production downtime. Saving = conventional total minus RetroSeal total.
- Person-hours include fitting or replacement and the additional testing labour. Production downtime is calculated separately from labour time.
Keep replacement and testing times separate to avoid counting the same work twice. The example scenarios assume that RetroSeal avoids conventional re-testing, permit and production downtime costs; edit the additional RetroSeal fields when that assumption does not fit your site.
