Union 32mm RAKtherm PPRc

A Union 32 mm RAKtherm PPRc PN 25 is a detachable pipe fitting used to join two 32 mm PPRc lines while allowing future disassembly for maintenance, pump removal, valve replacement, or equipment servicing.

What it is

Main specifications

The 32 mm size is commonly used in building services, chilled water branches, and medium-size domestic distribution lines, especially where equipment needs periodic removal.

Description and usage

This fitting is used where you want a strong permanent pipe connection but still need the ability to open the line later. That makes it very useful near pumps, filters, heaters, manifolds, and control equipment in HVAC and plumbing systems. In hot and cold water networks, it helps reduce downtime because you can service a component without replacing a long section of pipe.

Installation

1. Cut the 32 mm pipe square and clean the ends.

2. Socket-fuse the PPRc ends according to standard PPR welding practice.

3. Make sure the union sealing faces are clean and aligned.

4. Tighten the union nut by hand first, then snug it without over-torquing.

5. Pressure-test the system before commissioning.

For PPR systems, the welded portion must be fully cooled before applying load, and the union should be tightened evenly so the sealing ring seats properly.

Practical notes

• Use a union where future maintenance is likely.

• Keep the union accessible; do not bury it in inaccessible walls without an inspection point.

• Verify that the exact union style matches the mating part, because some unions are weld-by-weld, while others are weld-by-thread or have brass inserts.

• For procurement, confirm the exact seal type, end configuration, and whether the fitting is a true union or a transition union
