Connector straight compression with female thread Comap 20 mm x 3/4" (model 9462516)

Straight compression connector with internal (female) thread by Comap, designed to join a 20 mm pipe to a 3/4" threaded fitting. The connector uses a compression fitting principle to create a compact mechanical seal without soldering or adhesives. It is intended for plumbing and central heating installations where materials are compatible and potable water is involved.

Advantages

The compression design provides a reliable mechanical seal suitable for quick installation and maintenance. Internal threading allows direct connection to 3/4" threaded valves, taps or fittings without additional adapters. The straight configuration keeps the waterway unobstructed and reduces pressure loss. The connector is compatible with common pipe types used in water and heating systems when installation instructions and material compatibility are observed.

Suitable for

• Connecting a 20 mm pipe to a 3/4" threaded valve or fitting
• Domestic potable water supply lines
• Central heating circuits where compression fittings are specified
• Repair or modification of existing plumbing runs requiring a compact connection

Key specifications

• Connection type: straight compression on pipe side, internal (female) 3/4" thread on fitting side
• Pipe nominal size: 20 mm
• Thread size: 3/4" internal thread
• Sealing method: mechanical compression seal (no soldering required)
• Typical applications: potable water and central heating systems

How to use

Ensure the pipe end is cut square, deburred and free of damage. Slide the compression nut and olive onto the pipe, insert the pipe fully into the connector body, then hand-tighten the nut onto the connector thread. Use an appropriate wrench to tighten to the manufacturer’s recommended torque or until a leak-free mechanical seal is achieved; avoid overtightening which can deform the pipe or olive. Connect the 3/4" threaded component to the internal thread and secure according to the fitting’s instructions. After installation, pressurize the system and inspect for leaks at ambient and operating temperatures.

Usage recommendations

Verify material compatibility between the connector and piping (for example copper, PEX or suitable plastics) before installation. Use correct-sized olives and nuts supplied for a 20 mm pipe and follow local plumbing codes. If uncertain about the installation or if the system operates at higher temperatures or pressures than typical domestic use, consult the product documentation or a qualified installer.
