Description
Overview:
The Inline Lever Ball Valve 3/8" BSP Female Thread is a compact shut-off valve for isolating and controlling fluid lines on tools, plant and workshop systems. It features a durable brass body with a red lever handle for quick quarter‐turn operation. Both ends are 3/8 inch BSP female threads (approx. 9.5 mm nominal), allowing straightforward in-line connection to standard BSP pipework and fittings. The inline layout keeps pipe runs tidy and reduces the space needed for installation. Suitable for water, air and many non-corrosive oils, it is commonly used across construction equipment, garden machinery and general plumbing on compressors, pumps and spraying gear. Designed for repeatable, leak-tight operation and easy servicing, it offers reliable performance in day-to-day use. MPN: 850 038.
