Description
Overview:
This Leather Washer 1" is a durable sealing washer for plumbing pipe work. Made from high-quality tanned leather, it compresses to form a tight seal between flat-faced fittings and threaded unions, helping prevent leaks in domestic, commercial, and site setups. The washer has an outer diameter of 1 in (approx. 25 mm), an inner diameter of 20 mm, and a depth of 4 mm, giving a solid sealing face while remaining flexible. Supplied under MPN 830 100, it is suitable for use in pipe connections, valves, unions, backnuts, and other fittings where a resilient, natural fibre washer is preferred. It is a practical choice for both DIY users and tradespeople who need a reliable, simple-to-fit sealing component for general plumbing maintenance and repairs.
Key Features:
- High-quality tanned leather for a robust, flexible seal
- Dimensions: 1 in OD (approx. 25 mm), 20 mm ID, 4 mm thickness for reliable seating
- Compressible material conforms to minor surface imperfections to reduce leaks
- Suitable for flat-faced unions, backnuts, tank and pipe connectors, and similar fittings
- Simple drop-in replacement for worn washers; no special tools needed
- Helps maintain joint integrity under vibration and minor movement
- Resistant to water exposure and designed for long service life in typical plumbing use
- Natural fibre construction avoids cold-flow associated with some synthetic washers
Typical Applications:
Used to seal plumbing connections in stop taps, service valves, union joints, tank connectors, and hose tails. Suitable for maintenance tasks on domestic and light commercial pipework where a leather sealing face is required. Ideal for creating leak-resistant joints on threaded fittings and adapters in kitchens, bathrooms, utility rooms, gardens, and on-site temporary supplies.
