Description

Heldite H2OK is a WRAS‑approved, silicone‑based jointing compound for sealing bolted, flanged, and threaded pipe joints in potable‑water systems. It’s non‑toxic, water‑resistant, and does not support microbiological growth, making it ideal for hot and cold drinking‑water installations and low‑pressure steam.

Compatible with most metals, plastics, and rubber, H2OK provides a durable, leak‑proof seal and has been independently tested to BS 6920:2014 Parts 1–3 for water quality performance up to 85°C.
