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 HDPE pipes be connected 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.

Are SUNPLAST HDPE fittings UV resistant?

Yes, they are UV resistant and stable. Long-term 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 made of virgin PE100 material, designed for a 50-year lifetime. SUNPLAST provides a 10-year warranty for regular use.
