No, typically only two wrenches are needed – one to hold the fitting and another to tighten the compression nut. No soldering or gluing is required.
This coupling is designed for use with standard 22mm copper pipes. It can also be used with compatible PEX or plastic pipes, provided they meet the 22mm outer diameter specification and are rated for compression fittings.
It means the fitting compresses onto a pipe (the 22mm end) and has a female threaded connection (the 3/4" end) designed to receive a male threaded pipe or fitting.
After hand-tightening, use a wrench to turn the nut approximately 1 to 1.5 additional turns. Avoid excessive force, as overtightening can damage the pipe or the fitting.
No, this fitting is specifically designed for water systems and is not suitable for gas line applications.
The olive is a brass ring that deforms under the pressure of the compression nut. It bites into the pipe and creates a watertight seal against the fitting body.
This fitting is designed for standard domestic water pressures. For high-pressure industrial or specialized systems, consult a qualified plumber and check system-specific requirements.
Ensure the pipe end is clean and squarely cut. Check that the olive is correctly positioned. Try tightening the compression nut a quarter turn at a time. If the leak persists, the olive or pipe end may be damaged and require replacement.
Ensure the threads on both the nut and the fitting are clean and free from debris. Verify you are using the correct size wrench and that it is properly seated on the nut.
Confirm the pipe diameter is correct (22mm) and the fitting thread is correct (3/4"). Ensure the olive is the correct type for the pipe material and is not deformed or damaged. Re-ensure pipe preparation is accurate.
