Dome Top Gaskets

Don't throw away a lid just because your Dome Top P.R. valve is leaking! 9 times out of 10 the valve isn't leaking, it is the compression O-rings are leaking.
Here is a set of Food Grade O-rings; 1 for the locking nut & 1 for the body (as an extra seal).

The large ring goes on the nut, the small one on the threads of the Valve Body. Insert the valve body into the lid hole, screw on the locking nut....NO MORE LEAKS!

Valve body & locking nut NOT included.
