    FAQs
    Will these CPVC fittings glue onto regular PVC piping?
    The CPVC fittings we offer will not glue on PVC schedule 40 pipe. The CPVC fittings we offer are Copper Tube Sized (CTS) and normal Schedule 40 PVC pipes are sized according to IPS (iron pipe size) standards which are slightly larger in diameter. CTS sized piping has the same outside diameter as copper piping. 1/2" CPVC fittings fit CPVC piping that is 5/8" O.D.. 1/2" Schedule 40 PVC fittings fit PVC piping that is 27/32" O.D.
    Can I use CPVC pipe/fittings for compressed air or gases?
    Although some people use CPVC piping for compressed air or gases, we are not aware of any fittings manufacturer that recommends it. We believe it is dangerous and absolutely do not recommend it. Air is much more compressible than are liquids and could therefore cause a violent explosion.
    I get confused about CPVC sizes. You say that yours is 'copper size' but then you say that it is 'schedule 40' which I always thought meant the same size as steel pipe like galvanized. Please help to understand?
    Schedule 40 is the class rating of the pipe in regards to operating pressure, operating temperature and wall thickness of the pipe. There are two "standard" sizes of CPVC; IPS (Iron Pipe Size) and CTS (Copper Tube Size), which makes it a bit confusing. CTS matches the outside diameter of "nominal" copper pipe and tube, which is the type we offer. For example, the copper tube size 1/2" CPVC that we sell has an outside diameter of 5/8" and the 3/4" CPVC outside diameter is 7/8". CPVC made to IPS (iron pipe size) standards match the outside diameter of PVC pipe and comes in Schedule 80. We do not offer fittings for IPS sized Schedule 80 CPVC. Please Note: CTS (Copper Tube Size) CPVC, where it is allowed by code, is acceptable for residential plumbing.
    I've had a few female adapters break. What am I doing wrong?
    Many codes (such as UPC 1994 sec606.2.2) prohibit female PVC screwed fittings for water piping. The reason is, pressure is exerted outwardly, and eventually a female adapter can crack. We always recommend using male adapters (with metal female fittings rather than the other way around). Never use regular female adapters with pressures over one pound.
    Do you recommend using PTFE thread sealing tape on CPVC threads?
    Lasco Manufacturing says (when speaking about a similar plastic, PVC): "It is wrong to add excess bulk to a threaded joint by wrapping male threads in Teflon® tape. It is wrong to make over-tightening easier by using Teflon® tape..." We have seen much similar PTFE thread sealing tape used satisfactorily but cannot (due to liability potential) recommend that you use PTFE thread sealing tape (pipe dope designed for CPVC, such as we offer here, is acceptable).
    Will CPVC pipe and fittings crack when it is frozen?
    Just like copper and all piping material, it will crack when frozen. We recommend you insulate your pipes in areas exposed to freezing conditions.
    Is there a more flexible type of plastic pipe that will work instead of this rigid CPVC pipe?
    There is a flexible plastic pipe available. It is a cross linked polyethylene pipe called PEX. Most PEX piping is sized like copper piping.
