Compression coupling for copper pipes INVENA 3/4" x 15 mm, 2 pcs (CZ-83-001)

Compression coupling for copper pipes INVENA 3/4" x 15 mm, pack of 2, is designed to create a reliable mechanical seal between 15 mm copper tubing and components with a 3/4" threaded interface where applicable. The fitting is intended for potable water and heating systems, allowing for joining, extending or repairing 15 mm copper lines without soldering. Supplied as two pieces, the coupling facilitates on-site installation and quick replacement of damaged sections.

Advantages

The compression coupling provides a leak-resistant connection through mechanical compression of the ferrule onto copper pipe, eliminating the need for hot work. Its compact size and straightforward assembly reduce installation time and tool requirements. The fitting is compatible with common 15 mm copper plumbing and is suitable for both potable water and heating circuits when installed according to applicable standards.

Suitable for

• Joining two 15 mm copper pipes in potable water systems
• Extending existing 15 mm copper lines in heating circuits
• Repairing localized leaks or damaged pipe sections without soldering
• Temporary or permanent connections where a 3/4" threaded interface is required

Key specifications

• Pipe connection size: 15 mm copper tubing
• Threaded interface: 3/4" where applicable
• Pack quantity: 2 pieces
• Connection type: compression coupling with ferrule
• Application: potable water and heating installations

How to use

Ensure pipes are clean, straight and cut squarely. Slide the nut and ferrule onto the copper pipe, insert the pipe into the coupling body until it seats, then tighten the nut to compress the ferrule and form a seal. Follow manufacturer torque recommendations when available and check for leaks under system pressure after installation. For mixed materials or special installations, use appropriate transition fittings and adhere to local plumbing codes.

Usage recommendations

Use the coupling only on sound, properly prepared 15 mm copper tubing and verify compatibility with the system’s working pressure and temperature. Do not overtighten nuts; inspect connections periodically and re-torque if necessary after initial system pressurization.
