    Q:Will this coupler work with an older yellow smooth wall poly pipe gas line with 5/8" OD?
    by|Apr 12, 2023
    1 Answer
    Answer This Question

    A:  Hi, Kirk - Given that the OD of your "older yellow smooth wall poly pipe" is 5/8" (.625), that would most likely indicate 1/2" CTS sizing. If that's the case, no the coupler you mentioned won't work as it's for 1/2" IPS sizing. We do, however, make a 1/2" CTS / IPS coupler. Check out part number 18-429-101, HD Sku # 1002288677 on homedepot.com.

            Q:Can this pipe be used in a crawl space
            by|Nov 8, 2021
            1 Answer
            Answer This Question

            A:  Hi, Jcoker - No. Our (and others) underground PE pipe should never be used in or under a building. Please refer to our HOME-FLEX System Design Installation manual available for viewing or download at homeflex.com. Suggest you consider Home Flex CSST (corrugated stainless steel) products for your in/under building needs. Please feel free to call me (Dave) at 661 257-3923 x 1026 M-F 8a-2:30p should you require further information. Thanks.

                  I was unable to get the couplers I normally use so I had to use these, they went on easy and tightened down very easily very little effort and held 20 psi for three days so I’m very pleased

                  Glad to hear that, Steve. We suggest that the system be pressure checked at 15 psi for 30 minutes. Longer (especially overnight) can render "false positives" given temperature and barometric changes. ValenciaPipe

                  Experienced at leak at one of these fittings. Ultimately identified a small nick on the plastic piece that creates the seal with the propane line. Ordered a new fitting and that resolved my issue.

                  Very simple to use. Just make sure you have the proper cutting tool very important.

                  Yep. We always recommend using a standard PVC cutter. Don't use a saw which creates small pieces that may inhibit a good, solid seal ValenciaPipe
