Can HDPE fittings connect directly to PVC or PPR pipes?

No. HDPE fittings can only connect to HDPE pipes via heat-fusion. They cannot connect directly to PVC or PPR pipes due to different material grades.

How can we connect HDPE pipes to PVC pipes?

Since they cannot be heat-fused, use a flanged connection method by employing HDPE flange adaptors and HDPE backup flanges to connect to PVC flanges.

What warranty does SUNPLAST provide?

All fittings are designed for a 50-year lifetime. SUNPLAST provides a 10-year warranty for quality assurance under regular use conditions.

Product Q&A

Q:Which SDR of HDPE fittings should be used for SDR13.6-PN12.5 pipe?

To guarantee safety, fittings must have equal or higher pressure rating than the pipeline. Use SDR13.6 or SDR11 fittings; SDR17 is not suitable for SDR13.6 pipe.

Q:What kind of HDPE pipe fittings does SUNPLAST provide?

We provide three types: Butt fusion fittings (50mm-800mm, SDR17/11), Electrofusion fittings (20mm-630mm, SDR11/17), and Compression fittings (20mm-110mm, PN16).

Q:Can SUNPLAST provide HDPE fittings in PE80 material?

Yes, PE80 fittings are also available from us.

Q:Can HDPE fittings made by PE100 material weld with pipes in PE80?

Yes, they can be welded together. However, for the best welding results, we recommend welding PE80 pipes with PE80 fittings.

Q:What is the difference between Butt fusion and Socket fusion female adaptors?

Butt fusion requires exact outer diameter match and has a long-spigot; Socket fusion allows outer diameter to be same or 1-2mm smaller than pipe inner diameter and has a short-spigot.
