PVC Compression Fittings

(AKA: Dresser Fittings)

PVC compression fittings may be a quick-fix in some emergency situations that require a temporary or even permanent repair in a hurry, with less down time. If you need to add a line by teeing into an existing line, no problem; just prepare your tee (either glue socket outlet or female pipe threaded outlet) by adding a valve, then turn off your water, cut your line and insert the tee, tighten the compression ends and turn the water back on. Use two male adapters and a threaded valve to quickly add a shut off when needed. Need other PVC fittings? View the best selection of PVC fittings on the Internet!

Please read: Plumbing codes do not allow for PVC compression fittings inside of walls nor inside a home/building. PVC is for cold water only and is not designed for distribution of compressed air or gas.

Frequently Asked Questions

Q. "Are there any precautions to take when using these compression PVC fittings?"
A. Yes, the pipe should be secured to prevent movement that can cause the pipe to separate from the fitting. This can be accomplished by strapping it to stakes on each side of the fitting or blocking the ends of the run where it stops or changes direction.

Q. "How do I use these PVC compression couplings?"
A. Watch as Aden shows you how to use both the standard and Spring Locking compression couplings to repair your PVC pipe.

Q. "Do you recommend using PTFE thread sealing tape on PVC threads?"
A. Lasco Manufacturing says: "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 PVC, such as we offer above, is acceptable).

Q. "What does the term spigot mean?"
A. The term spigot is used to describe one side of a fitting that is the same outside diameter of pipe and is used to glue directly into PVC fittings (slip or socket end).

Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.
