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.

How can we connect HDPE pipes 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.

Is 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 made of virgin PE100 material, 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 pipe fittings does SUNPLAST provide?

SUNPLAST provides three types: HDPE butt fusion fittings (50mm-800mm), HDPE electrofusion fittings (20mm-630mm), and HDPE compression fittings (20mm-110mm).

Q:Can SUNPLAST provide HDPE fittings in PE80 material?

Yes, PE80 fittings are also available from SUNPLAST.

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:Are HDPE end caps and HDPE pipe ends the same thing?

Yes, they refer to the same products.
