SANHA transition press fitting coupling Purapress ZW x GW 15 mm x 1/2" (182701512)

SANHA transition press fitting coupling Purapress ZW x GW 15 mm x 1/2" is a press-installation component designed to connect a 15 mm copper or compatible pipe to a 1/2" female threaded fitting. The fitting is intended for systems that use press technology to create sealed connections without soldering, providing a durable joint for potable water and heating installations where a transition from press-to-thread is required.

Advantages

The coupling enables a secure, leak-resistant connection between a 15 mm press pipe and a 1/2" threaded fitting using press tools, eliminating the need for flame-based joining methods. Its design ensures consistent sealing performance when installed with the appropriate press jaws and contributes to faster installation times compared with soldered joints. The transition element is suitable for potable water and heating systems and is made to meet the mechanical and dimensional requirements of press-fit installations.

Suitable for

• Connecting 15 mm copper or compatible press pipes to 1/2" female threaded fittings
• Potable water distribution systems
• Heating circuits where press-to-thread transitions are required
• Retrofit or repair work that replaces soldered connections with press technology

Key specifications

• Connection A: 15 mm press connection for copper or compatible pipes
• Connection B: 1/2" female threaded connection
• Type: Transition press fitting coupling (press-to-thread)
• Intended media: Potable water and heating medium
• Installation method: Press-fit using compatible press tools and jaws

How to use

Prepare the 15 mm pipe by cutting square and deburring the end. Insert the pipe fully into the press end of the coupling until it reaches the internal stop. Thread the 1/2" male fitting into the female threaded end and tighten to the required torque or hand-tighten as needed before final tightening. Place the appropriate press jaw over the press sleeve and perform the press operation according to the press tool manufacturer's instructions to form the permanent seal. Verify the connection visually and, where applicable, perform a pressure test of the system following installation standards.

Usage recommendations

Use only approved SANHA-compatible press tools and jaws sized for 15 mm fittings. Ensure all components are clean and free from damage prior to installation. Follow local plumbing codes and pressure-testing procedures after installation. Avoid using the fitting in systems with incompatible media or where materials specifications prohibit mixing of metals without appropriate corrosion protection.
