M22 SCREW COUPLING O-RING (THICKER) SEAL - B13.273

M22 Screw Coupling O-Ring (Thicker) Seal — B13.273 is the thicker replacement O-ring used inside M22F couplings on V-TUF pressure washer hoses, trigger guns and accessories.

Fits: V-TUF V1, V3, V5 and V7 pressure washer ranges — any M22 screw coupling that uses the thicker O-ring profile. Pairs with T4.015 (thinner M22 seal) to make a complete M22 coupling spare kit.

Key specifications:

• Type: O-ring, "thicker" profile
• Connection: M22 screw coupling
• Material: nitrile rubber

When to replace: Replace if water weeps from an M22 screw connection, or if a coupling drips even after being hand-tightened firmly. A worn or missing seal is the most common cause of M22 leaks.

What's included: 1 × M22 thicker O-ring seal.
