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.

How can HDPE pipes be connected to PVC pipes?

Since they are different materials, they cannot be heat-fused. 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 stable and will not structurally degrade. Surface may look waxy after long UV exposure, but this does not affect performance and can be scraped off before welding.

What warranty does SUNPLAST provide?

All fittings are made of virgin PE100, designed for 50 years of use. SUNPLAST provides a 10-year quality warranty for regular use.
