Description
Overview:
These Copper Washers 16x22x1.5mm are solid copper sealing washers used to create a tight, leak-resistant seal in fuel injection assemblies and other fluid connections. Made from high-quality copper, they compress slightly under load to fill surface imperfections, helping to prevent leaks at banjo unions, injector lines, pumps and filter housings. Their corrosion resistance makes them suitable for diesel and petrol environments as well as light oils and coolants commonly found in construction and garden machinery. Each washer measures 16 mm inner diameter, 22 mm outer diameter, and 1.5 mm thickness, providing a consistent fit where a 16 mm ID seal is specified. Supplied in a pack of 50 for workshop convenience. Manufacturer Part Number: 915 421.
Key Features:
- 16 mm ID x 22 mm OD x 1.5 mm thickness for accurate, repeatable sealing
- Solid copper construction for reliable crush and long-term corrosion resistance
- Helps prevent fuel and oil leaks at banjo bolts, injector lines and pump connections
- Smooth, flat faces for consistent gasket compression and sealing performance
- Suitable for diesel and petrol systems, plus light oils and coolants
- Works with many plant, agricultural and garden engines using 16 mm ID washers
- Simple to install; fit between mating faces and torque to the equipment specification
- Pack of 50 to cover routine maintenance and multiple repairs
- Stable sealing after heat cycles typical of engine bays and machinery compartments
- Useful stock item for workshops, mobile engineers and DIY users
Typical Applications:
Used on diesel injectors and return lines, high-pressure pump fittings, fuel filter banjo unions, and other fluid couplings requiring a 16 mm internal diameter washer. Also suitable for sealing low- to medium-pressure oil and coolant lines on engines, generators, compressors and similar machinery where copper crush washers are specified.
Also known as:
Copper crush washers, copper sealing washers, copper sealing rings, copper gaskets, fuel banjo washers, injector line washers, copper ring seals, compression washers for fuel systems.
