Questions & Answers

Can i use this product to connect to the pressure relief valve on a water heater
ByMar 3, 2026
1 Answer | 
Answer This Question

Typically, the pressure relief valve connects directly to the water heater without the need for additional fittings. However, if you need to transition from 3/4 in. CPVC to male threads, this fitting would be a suitable option.

    will it work on a washer hose

    We would need more information to give an accurate response. Please contact our customer service, 888-229-2874.

    By|Jan 8, 2025

      A washing machine typically uses hoses with female threaded connectors. This adapter has a male threaded end, so it won't directly connect to a washer hose. You would need an additional adapter with a female threaded connection to make it work.

      CPVCMA34. NSF 14 is stamped on this Cpvc male adapter, but Apollo website says it has NSF 61. Which information is correct? Does NSF 14 also include potable water designation?
      ByApr 3, 2024
      1 Answer | 
      Answer This Question

      Its both NSF 14/61. NSF 14 focuses on the quality and performance of plastic pipes, while NSF 61 is specifically concerned with the safety of drinking water systems

        Will this adapter fit in a 1/2 in. FIP Inlet x 3/8 in. Comp Outlet Multi Turn Angle Valve ?
        ByMar 16, 2024
        1 Answer | 
        Answer This Question

        No. This adapter has a 1/2" CPVC slip connection and a 1/2" male pipe thread (MPT) connection. It won't fit a 3/8" compression outlet. You would need a different adapter with a 3/8" compression connection.

        Can this be used to transition from water heater exhaust valve to CPVC on wall?
        ByMar 12, 2024
        1 Answer | 
        Answer This Question

        This fitting is designed for use with water supply lines, not exhaust vents. Water heater exhaust vents typically require specialized fittings and materials that can withstand high temperatures. Using the wrong type of fitting could be a safety hazard.

        Are the threads right handed or left handed
        ByFeb 18, 2024
        1 Answer | 
        Answer This Question

        The threads on the 1/2 in. x 1/2 in. CPVC CTS Slip Stainless Steel MPT Adapter are right-handed.

        By|Feb 3, 2025


        Are the threads tapered or straight?
        BySep 13, 2023
        2 Answers | 
        Answer This Question

        They are listed at "pipe thread" which means they should be tapered.

        By|Jan 4, 2025

          The threads on the male threaded portion (MPT) of the adapter are tapered. This is standard for pipe threads (NPT/MPT) to create a watertight seal when tightened.

          Can this adapter be used for hot water line?
          ByJun 15, 2023
          1 Answer | 
          Answer This Question

          The CPVC fitting has a working temperature of up to 200 degrees F. So as long as you don't exceed that.

            I had a broken cpvc line for an outdoor hose faucet. The adapter was easy to install and attached to the new faucet.

            use extra teflon tape
            I connected this to a brass valve in my project to replace my main water line CPVC valve with a brass valve. unfortunately, I did not use enough Teflon tape on the male side of the adapter and now I have a dropwise leak. however, I noticed that both of the male adapters are having drippage leak that is getting worse every day. And I applied 3 to 4 layers of Teflon tape so either I did not put enough tape or these adapters have some flaw.

              Adapter is not stainless steel
              Metal portion of the adapter is not stainless steel as outlined in the description. Received a brass adapter instead. Thought I might have been delivered the wrong part so I went my local store but all they had were brass. Website needs to be updated to display the correct info.

                This is a very good quality, plumbing item, and that it solves the connection problems in one piece versus buying a lot of different pieces and gluing them together.

                Worked great and probably better overall than a conventual fitting. I only bought this fitting because the Home Depots close to me did not have in stock any conventional fittings in this configuration. For water heaters this is a very common fitting and Home Depot should always have this conventual fitting in stock. So because of this I had to spend more money.
