How to pick the right one
Frequently asked questions
What is the difference between Schedule 40 and Schedule 80 PVC fittings?
Schedule 80 has thicker walls and higher pressure ratings. It is more durable but more expensive. Schedule 40 is common for drainage and low pressure water. Schedule 80 is used for industrial and high pressure applications.
Can I use push to connect fittings on copper pipe?
Yes, push to connect fittings like SharkBite are designed for copper, PEX, and CPVC. You must cut the pipe cleanly and deburr it. They are approved for underground use if wrapped properly, but some codes prohibit them in concealed spaces.
How do I choose between threaded and slip fittings?
Threaded fittings are for metal pipes and allow easy disassembly. Slip fittings are glued for plastic pipes and create a permanent bond. Threaded requires thread sealant and proper alignment. Slip needs primer and cement. Consider future maintenance needs.
Are brass fittings better than stainless steel?
Brass is easier to machine and less expensive. Stainless steel is stronger and more corrosion resistant. For potable water, lead free brass is common. For chemical or saltwater environments, stainless is preferred. Cost and availability often decide.
What does NPT mean on pipe threads?
NPT stands for National Pipe Thread, a standard for tapered threads. It creates a seal when tightened. Use thread sealant tape or paste to prevent leaks. NPT is common in North America for metal pipes.
Can I use galvanized fittings for natural gas?
Galvanized fittings are not recommended for gas lines. The zinc coating can flake and clog orifices. Black iron or steel is the standard for gas. Some codes allow galvanized above ground, but it is safer to use black iron.
How do I measure pipe fitting size?
Pipe size refers to the nominal inside diameter, not the actual outside. For example, 1 inch PVC has an outside diameter of about 1.315 inches. Use a caliper to measure the diameter and refer to a chart to determine the nominal size.
What is a dielectric union and when is it needed?
A dielectric union connects dissimilar metals to prevent galvanic corrosion. It has an insulating gasket between the two sides. Use it when joining copper to steel or galvanized pipe. It is required by many plumbing codes.
Final word
Go with the Dixon Valve Camlock Type A if you need a reliable quick connect for transfer jobs. For permanent plumbing, choose Apollo press fittings for speed and code compliance. For a budget friendly option, Lasco PVC couplings work well for drains. But for overall contractor versatility, SharkBite push to connect fittings save time on repairs and are worth the extra cost.
