Q&E PPSU Fittings for Pexa Systems
PPSU fittings are made from special polymer - Polyphenylsulfone (PPSU).
Using PPSU pipe fittings to connect with PEX pipe are characterized by high impact strength, high temperature resistance(up to +170 ° C) and exposure to aggressive environments. Like other plastic products, PPSU is not subject to corrosion. PPSU compounds are also UV resistant and sediments of mineral substances dissolved in water.
Various types of PPSU products are widely used in food processing equipment(dairy machines, filtration panels, heat exchangers) and for medical components products subject to repeated cleaning and sterilization: attachments for endoscopic holders surgical devices, handles for dental and surgical instruments.
Such modern plastics are successfully replacing metals, providing significant economic- the range of traditional materials, energy resources, labor costs and operating costs. Our PPSU pipe fittings are designed for using in cold and hot water supply, radiator and underfloor heating systems.
Specifications of PPSU fittings:
• maximum allowable working pressure: 10 bar;
• test pressure is 16 bar;
• maximum permissible temperature of the transported medium: 95 ° С;
• service life: 50 years (subject to the temperature conditions given in GOST 32415-2013);
• melting point +170 ° C;
• approved for use in drinking water supply systems;

- Ritable PPSU fittings are made by injection molding using high strength engineered plastic with high design flexibility and a wide range of options of fitting type and structure.
Easy instruction and ensure system's safety, saving much installation time.
Reduce the number of fittings in system and reduce the risk of leaking in the system.
Health and safety like baby care
PPSU materials are often used as nursing bottles or cups for heat-resistant temperatures up to 404.6ºF(207ºC). This material has an outstanding performance in human health high temperature resistance,resistant to hydrolysis and impact resistance.
- very good sound and electrical insulation of installation thanks to using PPSU fittings
- significant savings of heat, PPSU material is characterized by greater thermal resistance as compared to brass so fittings give less heat back
- durability and high quality of PPSU fittings of KAN-therm system confirmed by Polish certificates and examinations in the reputed European Institute KIWA
- 100% reproducibility of product, production technology of PPSU fittings practically excludes any latent defects
Installation Instructions
Step 1
Use pipe cutters to make a square cut of the pipe to length. A rough or uneven cut can result in a weakened joint.
Step 2
Slide your expansion ring over the PEX tubing until it overhangs the end of the tubing by no more than 1/8 inch or until the stop on the ring (if present) touches the tubing.
Step 3
Using an approved manual or cordless expansion tool, insert the tool into the PEX pipe and expand the pipe. Note that each pipe size requires a specific expander head, so ensure that it is the correct size before beginning. The number of expansions will be dictated by the tubing size (6 expansions for 1/2 in., 8 expansions for 3/4 in. and 5 expansions for 1 in.). It is important to make sure the expander head rotates after each expansion to prevent ridges on the inside of the tubing.
Step 4
Once the tubing is expanded, insert the fitting until it hits the shoulder and allow the PEX to contract around the fitting until secure. After several seconds, the tubing will secure around the fitting and your connection is made and ready for use.
Q1. What material of pipe are you specialized in?
A: We manufacture PE-Xa, PPR, PE-RT, PEX Aluminum composite pipes and fittings.
Q2. Do you produce PVC pipes and fittings?
A:Sorry, dear friend. We are more professional PE and PPR pipe and fittings, which are more suitable for drinking water as they are more hygienic than PVC material.
Q3. Please tell me your largest outer diameter for pipes.
A: We can produce 8mm-- 110mm diameter (PE pipe).
Q4. The price of your products is higher than others.
A: We can't promise you the best price, but we can promise you the best quality. We import raw material from famous companies such as Borstar, LG Chemical, Chervrom, Hyosung, Lydellbasell, Sinopec.
Q5. For pipe fittings, what do you do mainly?
A: For fittings, coupling (socket), elbows, tee, reducer, union, valve, cap and copper insert fittings are our main products.
Q6: Can you provide us some samples for testing?
A: Of course, my friend. For small amount of samples, we can provide you for free.
Q7: How is our customer service?
A: all our sales representatives can speak fluent English. They will answer all of your questions in 24 hours.
