Frequently asked questions
What is the difference between pipe fittings and pipe connectors?
Pipe fittings is a broad term that includes connectors, adapters, elbows, tees, and more. Connectors are a type of fitting that join two straight sections of pipe. So all connectors are fittings, but not all fittings are connectors.
Can I use PVC fittings for hot water?
No, standard PVC is not rated for hot water. Use CPVC, which is specifically designed for hot water, or PEX or copper. Check the temperature rating on the fitting.
What does NPT mean?
NPT stands for National Pipe Thread, a U.S. standard for tapered threads used on pipes and fittings. The taper creates a tighter seal when tightened. It is widely used in North America.
Do I need Teflon tape on all threaded fittings?
For metal threaded fittings, it’s recommended to use Teflon tape or pipe dope to ensure a leak-free seal. For plastic threaded fittings, it may not be necessary, but it can help. Always use sparingly to avoid overtightening and cracking.
What is the maximum pressure for push-to-connect fittings?
Most push-to-connect fittings are rated for up to 200 psi at temperatures up to 200°F, but check the specific product specifications. Some brands may have lower ratings.
Are galvanized fittings safe for drinking water?
Galvanized fittings can be used for drinking water, but over time, zinc can corrode and cause lead or cadmium leaching if the coating is not food-grade. Modern regulations often discourage galvanized for potable water, preferring brass or PEX.
How do I measure pipe fitting size?
Pipe fitting size is based on the nominal pipe size, which for NPT refers to the inside diameter of the pipe. To measure, you can use a caliper to measure the outer diameter and then refer to a conversion chart. For threaded fittings, measure the thread diameter across the threads.
Can I mix brass and galvanized fittings?
Mixing brass and galvanized steel can lead to galvanic corrosion, especially in water systems. It’s best to use a dielectric union when transitioning between dissimilar metals to prevent electrolysis.
Final word
For most DIY plumbing projects, the KES Pipe Fitting Set offers the best combination of variety, quality, and value. Its brass construction ensures long-lasting performance, and the range of sizes covers common needs. If you specifically need corrosion resistance for outdoor projects, choose the Mueller Proline galvanized set. For a budget-friendly option on drain lines, the DANCO PVC assortment is a solid choice. Avoid compromising on safety by using the right material for your application.
