How PVC Inserts Work

PVC compression inserts are small parts inserted into the end of a PVC pipe before the compression fitting is applied. Combined, they create a watertight connection free of any leaks while in action. For the best results, the insert needs to be sized to fit the inside diameter of the pipe snugly. When the compression nut is tightened, it compresses the ferrule (compression ring) against the pipe and insert, creating a watertight seal at the joint. This process ensures a durable, reliable connection that prevents leaks while the system is in use.

PVC Compression Insert FAQs

What are the benefits of using compression inserts?

Compression inserts make it easy to assemble your irrigation system without any special tools or expertise. These fittings don’t even require adhesives like PVC cement, making them easier and faster to install, especially for DIY projects. Compression inserts also ensure a tight seal between PVC pipes and fittings, preventing leaks.

What are some common types of PVC compression inserts?

Two common types of inserts are PVC compression couplings and PVC compression adapters. Compression couplings are used to connect two sections of PVC pipe without any glue or adhesive. Compression adapters are used to connect irrigation pipes to different types of fittings or to connect pipes of different sizes.

How do I stop my PVC compression fitting from leaking?

If your PVC compression fittings are leaking, it usually means that the seal isn't tight or secure enough. Compression fittings rely on a rubber O-ring to form a tight seal. If the O-ring is damaged, cracked, or worn out, it won’t provide a proper seal. Make sure that the O-ring is in good condition, then insert the pipe into the fitting, making sure that the pipe is fully inserted.
