What is Male Socket 75×2-1/2″ RAKtherm PPRc ?
A Male Socket Brass Male Adaptor (threaded) 75×2‑½″ RAKtherm PPRc PN 25 is a transition fitting that connects a 75 mm PPR‑C pipe (by heat‑fusion socket) to a 2½″ external (male) brass thread, rated PN 25 (25 bar at 20 °C), imported from UAE for hot & cold water and HVAC water‑supply systems.
Product description Male Socket 75×2-1/2″ RAKtherm PPRc
-
Type: PPR‑C male adapter (male socket / male adaptor) — one side is a 75 mm PPR socket for fusion, the other side is a 2½″ male brass thread.
-
Material:
-
Body: polypropylene random copolymer (PPR‑C) for the socket end.
-
Thread insert: brass (often nickel‑plated) for corrosion resistance and durable threading.
-
-
Pressure rating: PN 25 = nominal 25 bar at 20 °C for water; pressure rating decreases at higher temperatures (derating applies).
-
Use: Hot & cold water systems and plumbing connections to threaded fixtures, valves, pumps, meters, manifolds, or equipment with 2½″ female threads.
-
Origin: Imported from UAE under the RAKtherm brand (Q‑Therm / RAKtherm PPR‑C line).
Key specifications (typical / to confirm on RAKtherm datasheet)
Note: Exact dimensions (overall length, socket depth, thread length, wrench flats) and the exact pressure‑vs‑temperature derating curve should be taken from the RAKtherm product datasheet for PN 25 fittings.
Installation guide (practical, step‑by‑step)
-
Select compatible pipe and fittings
-
Use 75 mm PPR‑C pipe and PN 25 PPR‑C fittings of the same brand/series (RAKtherm/Q‑Therm) to ensure compatibility and pressure rating.
-
-
Prepare the pipe and adaptor
-
Cut the 75 mm PPR pipe square, remove burrs, and clean the pipe end and the adaptor socket.
-
Mark the required insertion depth on the pipe (from the adaptor socket depth) to avoid over‑insertion or under‑insertion.
-
-
Set up the fusion tool
-
Use a socket fusion tool with the correct 75 mm heating die.
-
Set the heating temperature per RAKtherm instructions (typically around 260 °C for PPR‑C; confirm exact value).
-
-
Heat and fuse
-
Simultaneously insert the pipe end and the adaptor socket onto the heating die for the specified heating time.
-
Remove and quickly insert the pipe into the adaptor socket to the marked depth, holding straight and without twisting for the required cooling time.
-
Do not stress the joint until fully cooled.
-
-
Install the threaded side
-
Use appropriate thread sealant (PTFE tape or thread seal compound) compatible with potable water on the brass male thread.
-
Screw the adaptor into the female‑threaded equipment (valve, pump, meter, manifold, etc.) and tighten with a wrench on the hex flats designed for installation. Avoid over‑torque that could crack the PPR body.
-
-
Support and clamping
-
Provide proper hangers and supports for 75 mm PPR lines, including allowances for thermal expansion (sliding clamps where needed).
-
Avoid direct long‑term UV exposure; protect exposed runs.
-
-
Pressure testing
-
After installation, perform a hydrostatic pressure test per project specification and manufacturer guidance (typically at a test pressure lower than PN but sufficient to verify joints).
-
Inspect for leaks at the fused joint and threaded connection.
-
Usage and applications
-
Domestic and commercial hot & cold water distribution: connects large‑diameter PPR mains (75 mm) to equipment with 2½″ female threads (valves, pumps, meters, PRVs, manifolds).
-
HVAC water systems: chilled water, heating water, and plantroom connections where PPR mains interface with threaded steel/brass equipment.
-
High‑pressure risers and headers: PN 25 makes it suitable for high‑pressure cold‑water mains and hot‑water risers near pump rooms, where design pressures can be high.
-
Transition fitting: used as a reliable transition between PPR‑C piping and threaded metal components without reducing flow excessively (no internal reduction on the PPR side).
Important notes
-
Pressure derating: PN 25 is at 20 °C; for hot water at higher temperatures, the allowable operating pressure decreases. Use the manufacturer’s pressure‑vs‑temperature curve for design.
-
Thread type confirmation: Confirm whether the thread is BSPT (tapered) or BSPP (parallel) on the official RAKtherm datasheet, as this affects sealing method and compatible female fittings.
-
Food‑grade: Suitable for potable water if the fitting is certified food‑grade (verify certification on the datasheet or certificate).
