## Long description

Double-pass coupling 15 mm by No name (model 527015M) is a straight-through connector designed to join two aligned 15 mm pipes or tubes. Intended for plumbing and heating systems, this coupling creates a continuous flow path and a secure mechanical connection for small-diameter water or coolant lines. The product is appropriate for repair, extension, or replacement of existing 15 mm pipework where a reliable in-line joint is required.
Advantages
The coupling provides a compact and unobtrusive connection that maintains internal bore alignment for minimal flow disruption. Manufactured to fit standard 15 mm tubing, it simplifies installation by allowing a direct join without additional fittings. Its design offers mechanical stability and a leak-resistant interface when used with compatible tubing and appropriate sealing methods.
Suitable for
Repairing or extending domestic water supply lines with 15 mm pipe
Joining heating circuit pipes in radiators or underfloor systems with 15 mm tubing
Small coolant or circulation lines in equipment and appliances
Situations requiring an in-line, straight-through connection between two 15 mm tubes
Key specifications
Nominal tube diameter: 15 mm
Configuration: straight, double-pass (in-line) coupling
Intended media: water, coolant, low-pressure fluids
Application area: plumbing, heating, small-diameter fluid lines
Mounting: in-line mechanical connection for two aligned tubes
How to use
Ensure both pipe ends are clean, cut squarely and free from burrs. Slide the coupling onto one tube end and then align the second tube before fully seating the joint. Confirm that the tubes are inserted to the recommended depth and that any required sealing elements (such as O-rings, compression rings, or appropriate sealant) are in place according to the tubing type and installation practice. After assembly, test the connection under system pressure to verify there are no leaks.
Usage recommendations
Use the coupling only with compatible 15 mm tubing material and within the recommended pressure and temperature limits of the overall system. If unsure about sealing methods or compatibility, consult installation guidelines for the tubing type or a qualified installer. Perform a pressure test after installation and inspect periodically for signs of leakage or mechanical loosening.
