Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P
Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P (Product Code: SLE/WDF/16) is a straight polypropylene adaptor used to connect a 110 mm HDPE water pipe into a 4-inch female-threaded GI socket, valve or fitting. One end is a compression joint for the HDPE pipe and the other carries an external (male) thread, with a rating of 10 bar at 20°C, which makes it a simple in-line link between plastic mains and threaded metal hardware. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the HDPE to Male GI Thread Adaptor Used For?
HDPE pipe cannot be threaded, so wherever a plastic main has to enter threaded metal hardware an adaptor is needed. The Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P screws its male thread into a 4" female GI socket — for example a socket on a steel riser, the female end of a GI cross, bend or elbow, or a threaded valve body — and accepts the 110 mm HDPE pipe in its compression end.
Wrap the male thread with sealing tape and screw it into the metal socket firmly but without excessive force, since a plastic thread can be damaged by over-tightening. Then prepare the HDPE end with a square cut, chamfer and clean, and tighten it into the compression side. Where the adaptor enters heavy metal pipework, support the metal side so that the plastic body does not take bending loads.
What to Specify When Ordering
- The 4" female GI fitting or valve the adaptor will screw into.
- The number of HDPE-to-GI transitions on the layout.
- Operating pressure and temperature, to confirm they stay within 10 bar at 20°C and 0 to 50°C.

Frequently Asked Questions
Which ends does the Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P have?
The Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P has a compression end for 110 mm outside-diameter HDPE pipe and an external (male) thread for 4-inch nominal diameter GI pipe sockets. It is a straight fitting with no change of direction.
What does the male thread connect to?
The male thread of the Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P screws into a 4-inch female-threaded GI socket, fitting or threaded valve. Where the GI pipe presents a male end instead, a female-threaded transition fitting is needed.
What pressure and temperature is the adaptor rated for?
The Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P is rated for 10 bar at 20°C and a temperature range of 0 to 50°C. Keep pump and test pressures within this rating and allow extra margin in warm conditions.
What is the adaptor made of?
The Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P is reinforced, high-impact-strength polypropylene with UV stabilisation, so the body is tough and tolerates sunlight at above-ground connections such as pump outlets and tank risers.
Who supplies the Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P?
The Adaptor PP Comp, HDPE 110mmxmthd GI. 4"O/ND-P is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana. The company sources it and quotes it for water-supply projects and institutions in India and international markets.
