There are many different jointing/fittings styles for HDPE (high-density polyethylene), or HDCLPE (high-density cross-laminated polyethylene), which for many people is the preferred piping material for water or compressed air. The advantages of heavy-wall HDPE, especially for compressed air applications, include a smooth bore for reduced friction loss, it does not corrode, and it usually won’t stay crushed, like copper or steel, if it’s run into by heavy machinery.

Plasson’s new distributor Airquip and Pipetool have made an appearance online with a webstore for all major sizes of metric compression fittings and electrofusion fittings, plus a range of other fittings and couplings.
The range includes common configuration of electrofusion fittings, including the standard equal tees, elbows and connectors to the more specialist range of flanged tees, adjustable elbows, transition adaptors and tapping or branch saddles.
