Fernox Hawk White 400g is a general-purpose pipe jointing compound designed for sealing threaded metallic pipe joints and fittings.
It is suitable for use with natural gas, non-potable water, steam, air excluding medical lines, brine, alcohol and LPG. Hawk White can be used on pipework up to 25mm in diameter without reinforcement fibre. For pipework over 25mm, an approved reinforcing fibre should be used.
Hawk White complies with BS EN 751-2 Class A when used in the appropriate applications and provides a reliable seal for a wide range of plumbing and heating installations. It is supplied as a thick off-white paste in a 400g tin.
Important: Hawk White is intended for non-potable water applications. For drinking water systems, Fernox recommends Water Hawk instead.
Fernox Water Hawk is a pipe jointing compound specifically designed for use with hot and cold potable water. Its non-toxic formulation is WRAS approved, making it suitable for plumbing applications where the jointing compound comes into contact with drinking water.
Water Hawk is also suitable for use with natural gas, steam, air excluding medical lines, brine, alcohol and LPG. It can be applied directly to pipework up to 25mm in diameter. For larger pipework over 25mm, Fernox recommends using the compound with an approved reinforcing fibre.
The silicone-based compound is designed not to support microbiological growth, making it particularly suitable for potable water systems. It complies with BS EN 751-2 Class A for the applicable jointing applications.
