Product Information
Full details
The Pegler FW1 Fibre Washer is an essential component for professional plumbers and DIY enthusiasts working on domestic tap installations. Designed specifically for 1/2-inch tap connectors, it provides a dependable, leak-proof seal that prevents water waste and connection failure. While it is highly effective for standard plumbing, users should note that it is a single-use compression seal and must be replaced whenever a fitting is disconnected and reassembled to ensure ongoing joint integrity.

FAQs
Can I reuse a fibre washer?
No. Fibre washers compress during the initial installation. Once removed, they lose their ability to create a consistent seal and should always be replaced.
Is this washer compatible with 15mm pipes?
Yes, 1/2-inch tap connectors are the standard size used for 15mm plumbing connections in the UK.
Do I need to use PTFE tape with this washer?
No. The fibre washer is designed to create the seal on its own. Using PTFE tape on a captive nut connection is unnecessary and can sometimes interfere with the washer's ability to seat properly.
What material is the washer made of?
It is made of compressed fibre, which is an industry-standard material for ensuring watertight seals in plumbing joints.
Will this work for hot water taps?
Yes, these washers are suitable for both hot and cold water domestic plumbing applications.
Troubleshooting
Connection is still leaking after tightening
The washer may be misaligned or the nut may be under-tightened. Remove the connection, ensure the washer is sitting flat inside the nut, and retry.
Washer split during installation
This is often caused by over-tightening. Remove the damaged washer, clean the thread, and install a new one, applying only enough force to create the seal.
Pros and Cons
Pros
- Excellent seal integrity for 1/2-inch plumbing connections
- Compatible with major connector brands like Yorkshire and Endex
- Highly affordable and essential for routine maintenance
- Easy to install without specialized plumbing tools
Cons
- Designed for single-use; should not be reused after disassembly
- Not suitable for high-pressure industrial heating systems
- Requires proper tightening to achieve a full seal
Setup, Compatibility & Care
To install, ensure the mating faces of the tap connector and the pipe are clean and free of debris or old washer remnants. Place the washer squarely inside the nut before threading onto the male fitting.
Compatibility: This washer is strictly for 1/2-inch BSP threads commonly found in residential plumbing systems.
Care: Store in a cool, dry place to prevent the fibre material from absorbing moisture before use. If you detect a leak after installation, never attempt to reuse the washer by retightening; remove the connection, inspect the surfaces for damage, and install a brand-new washer.
