Hawk White General Purpose Threaded Pipe Jointing Compound (400g)

Hawk White Pipe Jointing Compound is a professional-grade, general-purpose sealing paste engineered for securing metallic threaded connections across a broad spectrum of commercial, domestic, and industrial pipework networks. Formulated with a classic linseed oil base, this thick, non-hardening paste smoothly fills the microscopic tolerances within metallic threads to prevent fluid and gas tracking. It comes highly recommended for registered gas installers (RGIs), mechanical contractors, and heating plumbers who require a dependable, multi-media jointing compound that complies with strict British and European safety standards.

Why Choose Hawk White Jointing Compound?

• Rigorous BS EN 751-2 Certification: Fully complies with BS EN 751-2 Class A benchmarks when paired with an approved reinforcing fiber. It is officially certified as a high-security sealing material for metallic threaded joints in direct contact with 1st, 2nd, and 3rd family gases.

• Excellent Thermal & Pressure Thresholds: Engineered to maintain absolute joint integrity under demanding operational loads. It safely seals gas connections up to 5 bar at 70°C, and hot water systems up to 7 bar at 130°C, making it ideal for central heating loops and plant room headers.

• Outstanding Multi-Media Versatility: This single compound handles an expansive list of service media, including Natural Gas, Liquefied Petroleum Gas (LPG), non-potable water, low-pressure steam, compressed air networks (excluding medical lines), brine, and alcohol.

• Flexible Application Rules: Offers the convenience of primerless, standalone application on small-bore pipe diameters up to 25 mm. For heavy-duty industrial pipework exceeding 25 mm, it works flawlessly when reinforced with plumbing hemp or flax fiber to bridge larger thread gaps.

• Lubricates and Protects Threads: The thick, smooth linseed-based paste acts as a high-efficiency lubricant during assembly, lowering frictional resistance so fittings can be screwed tight easily without galling, while actively protecting internal metal surfaces from rust.
