Q:is this union code? it says yout not supposed to splice ccst
by|Nov 16, 2021
1 Answer
Answer This Question

A:  Hi, nogoodnecktie - Our CSST Brass Union is specifically designed to join 2 sections of HOME-FLEX CSST pipe together. As for being to "code", all HOME FLEX CSST brass fittings meet all material and dimensional standards and should be used only with HOME FLEX CSST pipe. Should you have any other questions we'd be happy to assist via phone at (661) 257-3923 (x1026 and 1010) M-F 8a-5p. Or, you can always refer to our HOME FLEX CSST System Design & Installation Manual at homeflex.com. Thanks.

        Sorry to hear that Manso. We always suggest that the installer/user of the product refers to our CSST Design & Installation Manual and/or instructions included with our fittings (especially if using for the first time) for directions. ValenciaPipe

        Garbage
        Of all the brands for csst fittings homeflex are by far the worst. The seal to the fitting is one single retention ring smashed up against the flat metal seal, requiring 65llbs of pressure. There WILL BE leaks in your system using these. Additionally, if you need a replacement seal you have to buy them in a pack that only has one 3/4 set and one 1/2 set which is a total waste and upwards of 6$. I would HIGHLY recommend going with another brand like the one that loses carries.

          This union was garbage. I outfitted my whole house (4 gas appliances) with Home Flex CSST and not a single leak. This union has a slightly different design than any other fitting and it was awful to work with. I'm not sure why it has an o-ring in addition to the gasket but it makes installation near impossible. Couldn't get it to seal so I had to go another route.

          Hi, JB123 - We're sorry to hear you had an unfortunate experience with the CSST brass union. It is made exactly like the male and female fittings, so it would be interesting to know specifics. The o-ring was deemed as not integral to the sealing of the pipe and is being discontinued from the product. It can be used if it's provided but it'll do no harm if it's not. If you'd like to call our Technical Services Department, please call (661) 257-3923 M-F 8a-5p. Dave (x1026) or Jon (x1010). Thanks. ValenciaPipe
