Product Description

 

HDPE compression fittings, also known poly quick connect fittings, are designed for the jointing for HDPE pipes dedicated to water plumbing systems. They are normally used to convey drinking water and fluids at pressures up to 16 bar for generic applications.
 
Poly compression fittings are an age-old method of joining two pieces of poly pipe together, with an o-ring or bush and a screw cap working together to clamp the pipe ends within the fittings. With a clean pipe and a new fitting, the grip is strongest, and when properly installed, will last for many years without leaking. The fittings are mainly made of polypropylene black co-polymer (also called "PP compression fittings").
 
SUNPLAST HDPE compression fittings and clamp saddles are designed specifically for connecting polyethylene pipes with an outside diameter from 20mm to 110mm (max. To 315mm for clamp saddles). They are compatible with PE80 and PE100 pipes complying with ISO4427 standard. The quality of the PP-B material used makes SUNPLAST compression fittings resistant to etching by numerous chemical substances, and to UV-rays.
 
SUNPLAST HDPE compression fittings / PP compression fittings are are manufactured in compliance with the requirements of standards EN 712/713/715/911; ISO 3501/3503/3458/3459.The fittings can be installed on HDPE pipes which are in compliance with standards ISO 11922; DIN 8072/8074; UNE 53131. The threaded versions are manufactured in compliance with standard ISO 7; DIN 2999.

Benefits Of PP Compression fittings
By comparison of the other fittings, poly pipe compression fittings provide outstanding physical and performance benefits:
 
By comparison of the other HDPE fittings, HDPE electrofusion fittings repute more benefits:
* Fast assemble & disassemble, Simple installation:No welding, No special tools required, easily assembling & disassembling, those makes PP compression fittings more & more popularly used, especially for irrigation systems.
* lower installation costs & labor costs: HDPE compression fittings is a fittings use a mechanical connection method, fast to install & less install workers will be required.
* Perfect watertight: The unique design & NBR "O" rings ensure Poly compression fittings a perfect watertight for long time use.
 
 
FAQS


 
* How to connect the PP compression fittings?
A: PP compression fittings are very easy to install, which involves the following steps:
• Preparing the pipe, removing the burrs and beveling the edge of pipe. The outer surface of the pipe must be free from imperfections or indentations where the body of the fittings make contact with the pipe
• Unscrewing the blue nut and put it into the pipe followed by the white clamping ring. Make sure the clamping ring is in the correct position, with the larger mouth outwards to the edge of pipe.
• Pressing the pipe axially into the poly compression fittings, until it touch the internal gap of fittings.
• Tightening the ring nuts by hand, and then use the torque wrench provided, till it is tight.
 
* What is the most common cause of leaking of HDPE compression fittings?
A: It is critical to avoid over-tightening the nut or else the integrity of the poly compression fitting will be compromised by the excessive force. If the nut is overtightened the ferrule will deform improperly causing the joint to fail. Indeed, overtightening is the most common cause of leaks in PP compression fittings.
 
* How much burst pressure can Poly compression fitting take?
A: SUNPLAST PP compression fittings are designed for the max.normal pressure 16 bars at 20ºC, and the burst pressure reaches 35 bars.
 
* Can SUNPLAST HDPE compression fittings exposed under sunshine?
A: Yes, all HDPE pipe compression fittings are UV-resistant, and can be used outdoor.
 
* HDPE fusion fittings & HDPE compression fittings, which one is better?
A: It is hard to say. HDPE compression fittings are only be possible for small diameter pipe till 110mm, while HDPE fusion fittings are available for all sizes.
 
By comparison to HDPE fusion fittings, Poly pipe compression fittings are easy install, less cost, and are especially useful in installations that may require occasional disassembly or partial removal for maintenance etc., since these joints can be broken and remade without affecting the integrity of the joint.
 
The disadvantage is PP compression fittings are not as robust as fusion fittings.
