What are HDPE compression fittings?
Compression fittings are mechanical connection elements used to connect High-Density Polyethylene (HDPE) pipes in irrigation systems. They ensure a perfect seal by pressing a ring (O-ring gasket) onto the pipe by tightening a nut.

Do I need special tools to assemble HDPE fittings?
For small diameters (20mm - 32mm), compression fittings can be tightened firmly by hand only. For larger diameters or for increased safety in high-pressure networks, using a special wrench for fittings is recommended, but no thermal tools are needed.

What maximum pressure can HDPE irrigation fittings withstand?
Professional HDPE compression fittings are designed to withstand high working pressures, typically PN10 (10 bar) or PN16 (16 bar). This resistance makes them ideal for both residential networks and pressurized agricultural systems.

How to correctly install an HDPE fitting on a pipe?
Cut the pipe straight, slightly chamfer (round) the end, insert the nut and the clamping ring onto the pipe. Push the pipe firmly into the fitting until it passes the O-ring gasket (very important for sealing!), then tighten the nut manually or with a wrench.
