M15 Copper Sealing Washer 50 Pack
The Zoro Select M50301.150.0020 supplies fifty annealed copper washers sized for M15 fasteners. Each washer measures 15 mm inside diameter and 20 mm outside diameter with a uniform 1.5 mm thickness. The plain finish and copper seal material suit metric plumbing and hydraulic assemblies.
Suited for metric M15 joints needing a soft metal
Mechanics sealing brake lines, fuel fittings or hydraulic couplers on M15 threads will find the pack quantity convenient. Builders requiring a different bolt size, a larger outside diameter or a non-metallic gasket material should look at other listings.
Fifty washers cover multiple service jobs
The 50 pack handles several system rebuilds or a small fleet service without reordering. Copper compresses to seal minor surface imperfections but will not compensate for damaged threads or oversized counterbores.

Questions about this item
Does this pack include the M15 bolts these 15 mm ID washers seal against?
No, the pack contains 50 copper sealing washers only; M15 bolts are sold separately
Can these annealed copper washers be reused on an existing M15 fitting?
Reuse is not recommended because the 1.5 mm thick annealed copper deforms permanently on first torque
How do I confirm a proper seal after torquing the M15 joint?
Pressurise the system and check for leaks at the 20 mm OD sealing face
