Description

Overview

The M16 thrust washer forms part of the sealing arrangement used on metric male air fittings. It sits behind the matching O-ring and provides a firm support face as the fitting is tightened against the port. This shaped washer is intended for connection sealing, not as a general flat fastener washer or a rotating bearing washer.

Features

• M16 size for metric male air fitting connections
• Recessed circular profile supports the sealing O-ring
• Separate replacement component for damaged or missing sealing hardware
• Compact service part for truck and trailer pneumatic connections

See the GP Truck Products metric fitting guide for washer and O-ring sealing arrangements

Compatibility and Fitment

Compare the M16 thread application, centre opening, outside diameter and recessed profile with the original washer before ordering. An ordinary flat M16 washer is not a direct substitute because it does not provide the same seat for the companion O-ring. During assembly, place the O-ring correctly against the shaped face and keep both parts square to the port.

Compliance and Safety

Depressurise the air system before loosening or replacing a fitting. Clean the port face and inspect the washer for distortion, cracks, burrs or corrosion that could damage the O-ring. After assembly, restore pressure gradually and check the connection for leakage before returning the vehicle or trailer to service.

Trailer Applications

The M16 thrust washer suits truck and trailer air system connections built around a metric male fitting that seals with a thrust washer and O-ring. Workshops may replace it during fitting changes, adaptor replacement, brake valve plumbing or repairs where the original sealing hardware has been lost or damaged.
