Mine let go a few days ago. Thanks, Evan from NC ReplyQuote Topic Tags BAM B50 O-Rings Foster fitting nervoustrigger (@nervoustrigger) Mississippi Joined: 7 years ago Posts: 294 March 1, 2019 09:38:22 It is a -006. Use a 90 durometer. A softer O-ring is apt to extrude and fail. It will be difficult to get it on. Clamp the check valve in a vice so you have both hands free to install the O-ring, and warm the O-ring first in a cup of hot water.
