Compression Union Fitting Herz P 7016 11 — 16x2 mm to Rp1/2" External Thread

Herz P 7016 11 — 16x2 mm to Rp1/2" External Thread is a straight compression union fitting designed to join 16x2 mm metal piping to an external Rp1/2" threaded connection. Manufactured by Herz, the fitting creates a mechanical seal between press-fit or compression pipe and a standard half-inch external thread, enabling a reliable connection in plumbing and heating systems where a transition from tubing to threaded components is required.

Advantages

The compression design provides a secure mechanical joint without soldering or special tools, allowing for straightforward installation and maintenance. Constructed from metal suitable for potable water and central heating applications, the fitting offers corrosion resistance and dimensional stability under normal operating temperatures and pressures. Its straight union configuration simplifies alignment between pipe runs and threaded components, reducing the need for additional adaptors or fittings.

Suitable for

• Connecting 16x2 mm metal piping to external Rp1/2" threaded valves, appliances or fittings
• Domestic potable water lines where a threaded transition is required
• Central heating circuits for linking tubing to radiator valves or manifolds

Key specifications

• Connection A: 16x2 mm compression for metal pipe
• Connection B: external Rp1/2" (half-inch) thread
• Configuration: straight union fitting
• Material: metal suitable for water and heating systems
• Application: potable water and central heating installations

How to use

Prepare the 16x2 mm pipe end by cutting square and deburring the inner and outer edges, then slide the compression components onto the pipe as required. Thread the fitting onto the external Rp1/2" component by hand, then tighten to the recommended torque using appropriate wrenches to compress the ferrule and form a leak-tight mechanical seal. After assembly, pressurize the system and inspect the joint for leaks, retightening if necessary according to manufacturer practice.

Usage recommendations

Use compatible 16x2 mm metal pipe and ensure mating threaded components conform to Rp1/2" thread standards. Avoid overtightening to prevent damage to the ferrule or threads. Where required, follow local plumbing codes and manufacturer guidance for potable water and heating system installations.
