How can HDPE pipes be connected to PVC pipes?

Since they are different materials, they cannot be heat-fused. The solution is to use flanged connections with HDPE flange adaptors and backup flanges to connect to PVC flanges.

Are SUNPLAST HDPE fittings UV resistant?

Yes, they are UV resistant and stable. Prolonged UV exposure may cause a waxy surface look, but this does not affect performance and can be removed before welding.

What warranty does SUNPLAST provide?

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

Product Q&A

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

To guarantee safety, fittings must have an equal or higher pressure rating than the pipeline. For SDR13.6 pipes, use SDR13.6 or SDR11 fittings. SDR17 fittings are not suitable.

Q:What types of HDPE fittings does SUNPLAST provide?

SUNPLAST provides three types: Butt fusion fittings (DN50-800mm, SDR17/11), Electrofusion fittings (DN20-630mm, SDR11/17), and Compression fittings (DN20-110mm, PN16).

Q:Can SUNPLAST provide HDPE fittings in PE80 material?

Yes, PE80 fittings are also available from SUNPLAST.

Q:Can HDPE fittings made of PE100 material be welded with PE80 pipes?

Yes, they can be welded together. However, for the best welding results, it is recommended to weld PE80 pipes with PE80 fittings.

Q:Can HDPE fittings connect to PVC or PPR pipes?

No. Thermal plastic fittings can only connect to pipes of the same material grade. HDPE fittings can only connect to HDPE pipes, not PVC or PPR.
