Compression fitting Comap MultiSkin PPSU 20 — 20 mm plumbing connector

Compression fitting Comap MultiSkin PPSU 20 — 20 mm plumbing connector is a compact connection element designed for secure joints in potable water and heating installations. Manufactured with PPSU (polyphenylsulfone) components and precision compression rings, this 20 mm connector offers corrosion resistance and dimensional stability under normal domestic and light commercial conditions. The fitting is compatible with conventional 20 mm plastic and metal pipes where a compression-style seal is required and is intended for use in networks that transport drinking water or central heating fluids.

Advantages

This Comap MultiSkin PPSU compression fitting combines a high-performance polymer body with reliable compression mechanics to provide leak-tight joints without soldering or solvent welding. The PPSU material ensures good mechanical strength, resistance to aging and hot-water exposure, and low thermal expansion compared with some other plastics. Installation is generally fast and reversible, enabling maintenance or replacement of sections without cutting or heat-based joining methods.

Suitable for

• Domestic potable water supply lines with 20 mm pipework
• Residential central heating circuits using compatible 20 mm pipes
• Repair and modification of existing 20 mm plumbing runs
• Light commercial plumbing installations where a durable compression joint is needed

Key specifications

• Connection type: compression fitting for 20 mm pipes
• Body material: PPSU (polyphenylsulfone)
• Intended media: potable water and heating fluids
• Suitable pipe materials: common plastic and metal 20 mm pipes compatible with compression fittings
• Installation method: push-on with compression ring and nut, no soldering required

How to use

Prepare the pipe by cutting it square and removing burrs or sharp edges. Slide the compression nut and ring onto the pipe, insert the pipe fully into the fitting body until it seats against the internal stop, then hand-tighten the nut and complete the final tightening with a suitable wrench to the manufacturer’s recommended torque. After installation, check the joint for leaks by running the system under normal pressure and inspecting the connection. If disassembly is required, loosen the compression nut and withdraw the pipe; inspect or replace the ring before reassembling to ensure a reliable seal.

Usage recommendations

Use this compression fitting with clean, properly sized 20 mm pipes and avoid overtightening the compression nut. Verify compatibility of pipe material with compression fittings and follow local plumbing codes and pressure/temperature limits for potable water and heating systems.
