Can HDPE fittings connect to PVC or PPR pipes?

No. Thermal plastic fittings can only connect to pipes with 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 flanged connection with HDPE flange adaptors and HDPE 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 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.
