No more leaking fuel
These are a perfect fit and fix for my leaky Norton gas tank.

Triumph petcock washers
Good fit just like the originals.Lowbrow has great items at a good price, good selection.

sealing washer
they fit perfect and i had no problem installing them.

Love Lowbrow
Shipped the next day after ordering but haven't installed yet, however, everything I've ordered has been right on.

You need a flat washer too if you don't have it. petcock > flat washer > seal washer > tank
The washer's quality is good itself. I spent a few minutes twisting my petcock to get it as close as possible to make the seal and the washer was still loose. Partly my fault, I do wish the description could indicate that you need a flat washer as well for it to achieve a good seal though.

Good stuff
The items came fairly quickly and wor k just fine, very satisfied.

Petcock seals
The seals worked great

fuel taps
great service thank you
Motorcycle gas tank sealing washers
Great gas tank washers!
Great!
As always, I was very happy with the products - british style petcocks and sealing washers - and especially with the speed of filling and shipping the order. It helped me get the bike up and running quickly. I’ll be turning to you guys first when I need Triumph parts.
good service. good products.
good service. good products.
Don't forget the flat washers
My bike leaked fuel around the petcock area. I ordered new petcocks, sealing washers and the flat washers. Cleaned the threads in the tank with a 45 caliber bore brush installed the new parts dry, no more leak.
