Does not fit as described

By Bernie M.

from Vancouver, BC, CA

This is a smaller-sized valve, not standard size. It will only fit specific Hollis BCDs, better check the diameter of the threads of your dump access point: this valve has a diameter of 2", while the standard is 2-1/8".


Questions & Answers

Questions about this item:

Shopper  is compatible with seaquest pro bcd?
Bernie M  No, it is not. I ordered one specifically for this purpose, and it is too small; it appears to only fit specific Hollis BCDs. This one is 2" diameter, while the Seaquest is 2 1/8" diameter.
KEVIN F  No, we don't think it will fit. But, we do not have an old Seaquest Pro to verify.
