## Long description

Straight connector SiGMA-Li MZPZ251 for PEX piping provides a compact mechanical transition between a 25 x 1 mm PEX pipe and a threaded fitting. The connector features a male outer thread (GZ) designed to mate with standard female threaded valves, adapters and appliances. It is intended for plumbing and heating installations where a dependable sealed connection between flexible PEX tubing and threaded components is required.
Advantages
The connector offers a simple, space-saving design that facilitates a direct connection from PEX pipe to threaded fittings without the need for additional adapters. Its straight form factor reduces flow disruption and simplifies installation in confined spaces. The male thread ensures compatibility with common female threaded plumbing components and supports a mechanically stable joint when assembled according to recommended practices.
Suitable for
 Connecting 25 x 1 mm PEX pipe to female threaded valves and fittings

How to use
