PP · PE / Poly
PP Compression Fittings for PE & Poly Pipe — Reusable, Tool-Free, No Fusion
Polypropylene mechanical fittings that seal a PE / HDPE / poly line by hand — no electrofusion machine, no heat, no special tools, and fully re-openable for service.
Hitze PP compression fittings are polypropylene mechanical fittings for PE / HDPE / poly water and irrigation pipe. They seal by clamping the pipe with an internal grip ring and O-ring — no electrofusion, no butt welding, no heat, no special tools. Because the joint is purely mechanical, it is fully reusable: loosen, reposition and re-tighten for repairs, extensions or seasonal irrigation lines. The line covers reducing sockets and integrated valves across 20–110mm, making Hitze a single source for “pp compression fittings for pe pipe” and poly pipe compression fittings in bulk.

Brass · PEX / PE-RT
Nickel-Plated Brass Compression Fittings for PEX & PE-RT — Lead-Free, Potable-Rated
Compression-ferrule brass fittings for potable-water lines — no soldering, no crimp tool, re-tightenable for service, and machined from lead-free brass for drinking-water work.
For PEX and PE-RT lines, Hitze supplies nickel-plated brass compression fittings that seal on a compression ferrule and nut — no soldering and no crimp tool required, and re-tightenable for service. For drinking-water systems, our potable range is machined from lead-free brass certified to NSF/ANSI 61, so wholesalers and contractors can spec it into potable installs with confidence. As a brass compression fittings supplier, Hitze covers male/female/equal sockets, elbows, tees, wall-plate elbows and manifold ball valves across 16–32mm × 1/2″–1″, matched to the same overall program as our PP line for one consolidated order.
