What are HDPE fittings?
HDPE fittings join, turn, branch, reduce and close polyethylene pipes. They include elbows, tees, reducers, end caps, adaptors, flange adaptors and saddle clamps.
There are three main joint types. Compression fittings seal with a nut and O-ring, butt fusion welds pipe ends, and electrofusion uses fittings with built-in heating wires. Choose by pipe size, pressure and site conditions.

Key terms explained
- HDPE
- High-density polyethylene, a tough, flexible plastic used for water and gas pipes.
- PE100 and PE80
- Grades of polyethylene. PE100 is stronger, so pipes can have thinner walls for the same pressure.
- PN rating
- Pressure Nominal, the working pressure in bar, such as PN10 or PN16.
- SDR
- Standard Dimension Ratio: outside diameter divided by wall thickness. A lower SDR means a thicker, stronger wall.
- Butt fusion
- Joining two HDPE pipe ends by heating them and pressing them together.
- Compression fitting
- A fitting that seals on the pipe with a nut, split ring and rubber O-ring, with no heat needed.
Features and benefits
- Full range of shapes for HDPE systems.
- Compression, butt fusion and electrofusion types.
- Corrosion-free bodies.
- Threaded adaptors for metal transitions.
