10Mm X 3/8 Bsp Compression Female Coupler

10Mm X 3/8 Bsp Compression Female Coupler

The 10mm x 3/8" BSP Compression Female Coupler is a specialized transition fitting commonly used in oil-fired heating systems and small-bore plumbing. This fitting allows for a secure connection between standard 10mm copper pipe and a 3/8" male threaded component, such as an oil burner pump, a solenoid valve, or a manifold outlet.

Constructed from high-quality brass, this coupler provides a robust, mechanical joint that can withstand the vibrations and pressures typical of heating and fuel supply lines.

Key Features and Specifications

Size: 10mm Compression x 3/8" BSP Female Thread (FI).

Joint Type: Compression end (includes nut and copper/brass olive) x Parallel Female Thread.

Material: Heavy-duty forged brass for maximum durability and corrosion resistance.

Compatibility: Designed for use with copper pipe, and suitable for Kerosene, Gas Oil, and water.

Standards: Manufactured to comply with standard UK plumbing and oil installation dimensions.

Seal: The compression end creates a mechanical seal on the pipe, while the female thread typically requires a washer or jointing compound to seal against the mating male thread.

Common Applications

Oil Boiler Installations: Connecting the 10mm supply line to the 3/8" male inlet of an oil filter or a fire valve.

Burner Connections: Adapting 10mm soft copper pipe to fit directly onto 3/8" male threaded burner components.

Small-Bore Plumbing: Used in specialized equipment or vintage plumbing fixtures that utilize 3/8" BSP threads.

Compressed Air: Linking 10mm nylon or copper air lines to 3/8" male regulators or tools.

Essential Companion Products

Jointing: Heldite Jointing Compound (Essential for oil-resistant threaded seals).

Pipework: 10mm Soft Copper Oil Pipe (Plastic Coated).

Inserts: 10mm Copper Pipe Inserts (Recommended when using soft copper to prevent pipe collapse under the olive).

Tooling: Two adjustable spanners for "counter-tightening" the compression nut.
