What is an FIPT fitting?
FPT (FIPT) – aka Female (Iron) Pipe Thread. This is a type of threading that is found on the inside lip of a fitting, allowing connection to a MPT or male pipe threaded end. FPT/FIPT threading is commonly used for PVC and CPVC piping systems.
Can you overtighten PVC fittings?
Additional turns of the fitting cause the female threads to stretch, however. This stretching puts strain on the threads, and if tightened too much, there’s a chance the threading can split or break. This is why it is important to remember not to over-tighten PVC fittings.
What is the difference between FIPT and FPT?
PVC pipe has spigot ends and requires socket fittings to join. FPT or FIPT refers to a female pipe threaded connection. Connection is to a male pipe thread fitting. MPT or MIPT refers to male pipe threaded connection with threads on the outside of the fitting.
What is the difference between NPT and IPT?
NPT (National Pipe Threads) also abbreviated as IPT (Iron Pipe Threads) are tapered so that as you tighten NPT male and femal fittings the threads wedge themselves ever more-tightly together. On the other hand compression fittings and flare fittings use threads that are cut in parallel, without taper.
What is the meaning of a PVC fitting?
Polyvinyl chloride (PVC) is a familiar and versatile thermoplastic especially known as a piping and fitting material used for residential and commercial plumbing applications. In the same thermoplastic family to PVC is chlorinated polyvinyl chloride (CPVC).
Does threaded PVC need glue?
You cannot use PVC cement on threaded connections, as it chemically bonds PVC together, destroying the threads. Slip connections are easy to make, as all you need is a simple push to make a connection! These types of connections can be made permanent by using PVC primer and cement, two substances that go hand-in-hand.
How tight should PVC fittings be?
The right way to assemble a threaded PVC joint-Schedule 40 or 80 is finger tight plus one to two turns-no more. Two turns past finger tight plus the stress of the system pressure is within the tensile strength of one-inch PVC. The working pressure of PVC pipe is based on a 2000 psi stress level.
What does fipt stand for in PVC pipe?
The abbreviations simply stand for female inside pipe thread and mean that the coupling has female threads inside. A FIPT coupling has female threads on both sides, meaning that your pipe will need to have male threads on both sides. The pipe ends are simply screwed into the fitting to form the joint, no cement is necessary.
Can a fipt coupling be used on a Schedule 40 pipe?
A FIPT coupling has female threads on both sides, meaning that your pipe will need to have male threads on both sides. The pipe ends are simply screwed into the fitting to form the joint, no cement is necessary. All of our Schedule 40 fittings are NSF rated 14 & 61, which means they are certified for use with potable (drinking) water.
What kind of fitting is used for PVC pipe?
EPDM – (Ethylene Porpylene Diene Monomer) a type of rubber used for sealing PVC fittings and valves. Fitting – part of a pipe line used to fit together sections of pipe. Fittings can come in all shapes, sizes, and materials.
Which is the female side of a PVC fitting?
Fipt: Fipt is the term for the female threaded side of the PVC fitting. Female threaded PVC fittings have threads on the inside of the fitting, and can be connected to any PVC item that has a male (Mipt) end. Mipt: Mipt is the term used for a male threaded side of a PVC fitting.
