Can HDPE fittings connect directly 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.

How can we connect HDPE pipes to PVC pipes?

Since they are different materials, they cannot be heat-fused. Use HDPE flange adaptors and HDPE backup flanges to connect to PVC flanges via flanged connection.

Is SUNPLAST HDPE fittings UV resistant?

Yes, they are UV resistant and stable. Prolonged UV exposure may cause a waxy look on the surface, 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 pipe?

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

Q:What types of HDPE fittings does SUNPLAST provide?

We provide three kinds: HDPE butt fusion fittings (DN50-DN800, SDR17/SDR11), HDPE electrofusion fittings (20-630mm, SDR11/SDR17), and HDPE compression fittings (20-110mm, 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:Is HDPE end cap the same as HDPE pipe end?

Yes, they refer to the same products.
