Hawk Jointing Compound 400G

400g

Hawk White is the industry-standard, non-setting jointing compound designed for professional use in domestic and commercial plumbing and heating systems. This 400g tin provides a high-quality sealant that acts as both a lubricant and a gap-filler for threaded connections, ensuring a permanent, leak-free seal for water, natural gas, and low-pressure steam applications.

Key Features and Application
Compliance: Fully BS 6920 and WRAS Approved, making it completely safe for use with potable (drinking) water. It also meets EN 751-2 standards for gas applications.

Non-Setting Formula: Unlike hard-setting pastes, Hawk White remains flexible. This allows for the easy dismantling of joints even years after installation without damaging the threads or the pipework.

Versatility: Suitable for use on metallic threaded fittings (copper, brass, and steel). It is the preferred choice for sealing radiator tails and heavy-duty threaded valves.

Temperature & Pressure: Engineered to withstand temperatures up to 200°C and high system pressures, making it ideal for central heating manifolds and boiler connections.

Usage: Typically applied to the male thread of a fitting. For larger threads or reinforced seals, it can be used in conjunction with plumbing hemp.

The Installer's Advantage
Hawk White is a staple in every plumber's tool bag. Its smooth consistency makes it easy to apply evenly, and because it doesn't set hard, it effectively absorbs the vibrations and thermal expansion common in central heating systems. It provides peace of mind on large-scale installations where a single weeping joint could lead to significant property damage or system pressure loss.
