A:  Hi, Plumb - No. In the CSST product category, pipe and fittings have to be from the same manufacturer.

    Q:Can the cast brass fittings be reused? For example, when one is used can it be removed to install another tee fitting and then retighten and the compressed?
    by|Mar 13, 2023
    1 Answer
    Answer This Question

    A:  Hi Plumb - Yes, our CSST fittings may be reused so long as the fiber gasket is changed each time. A 1/2" / 3/4" combo gasket kit is available to Home Depot or at homedepot.com. FYI, we don't make a CSST tee fitting. It's important that a HOME-FLEX fitting be used only on HOME-FLEX pipe.

      Q:Will this work to transition from 3/4" black iron pipe to 1/2" HOME-FLEX line?
      by|Sep 12, 2018
      2 Answers
      Answer This Question

      A:  No. This is to go from 3/4 CSST to 1/2 pipe. You need the 1/2 CSST to 3/4 pipe.

      by|Jun 1, 2020

      A:  Hi Kevin, This fitting transitions from 3/4 inch HOME-FLEX CSST to 1/2 inch male pipe threads. This fitting attaches to 3/4 inch CSST and has 1/2 inch Male Pipe Threads on the other end. To transition from 3/4 inch black iron pipe, you will need to fit a 3/4 X 1/2 inch reducer coupler to the iron pipe. Off of the 1/2 inch female end of the reducer, you can fit the 11-436-005 1/2 inch Male Pipe Thread x 1/2 inch CSST fitting.

        Q:Is there a 3/4 by 3/4 fitting? Not a coupler, instead of this reducer.
        by|Jul 25, 2018
        1 Answer
        Answer This Question

        A:  There is a 3/4" CSST X 3/4" CSST coupler under part number 11-429-007. This will couple two ends of our 3/4" CSST together. There is a 3/4" Male Pipe Thread adapter under part number 11-436-007. This fitting turns the end of our 3/4" CSST into 3/4" Male Pipe Threads. There is a 3/4" Female Pipe Thread Adapter under part number 11-435-007. This fitting turns the end f our 3/4" CSST into 3/4" Female Pipe Threads. You can couple two male adapters together by using a black iron coupler. You can couple two female adapters together by using a pipe nipple. You can even connect one of our male adapters to one of our female adapters. If this still does not accomplish what you want, you had better give me a call, so we can figure it out. I am here from 8-5 Pacific Time M-F. (661) 257-3923 Ask for Jon.

          This thing is garbage. First, half of the fittings in the store did not have all the components required to make the connection. Then, after 3 trips back to the store, we tightened the connects and this crappy split ring twisted into irreparable scrap.

              Works As described, I’ve read a few reviews complaining about leakage after installing? Attention to detail, you have to screw the nut onto the fitting, not the other way around or you will destroy the compression seal on the fitting. These seals are the same style we used on our Tanks, & Bradleys while I was in the military. So I know they work.. Way better than the old black pipe!

              Hi, KerinsEverydayServicesLLC - While we appreciate your review and input, our HomeFlex CSST system is designed for not only the professional but also for the handyman as well. It's not a complex installation process but does require some knowledge and/or research as to how to properly (and safely) configure a system that will work well with one's particular parameters. As with any product line, adhering to proper installation instructions is a key component of a safe and gas-tight system. All our CSST fittings are designed with a secure connection in mind and the vast majority of installations are completed with absolutely no failures by homeowners, handymen, and professionals alike. That having been said, we always invite (and suggest) that our customers review our handy HomeFlex CSST Design & Installation manual to address any questions and concerns. It can be viewed/downloaded at http://homeflex.com/downloads/HOME-FLEX_Installation_Manual.pdf. Thanks again for your review. ValenciaPipe

              The piping works great and is easy to connect by following the instructions. I had no leaks after pressure testing it. The only complaint that I have are the limited number of fittings. I had to go through all the boxes that were stored very high and hard to reach to find the last two fittings.
