Polypropylene Lever Valve with Stainless Steel Ball, 4"

Constructed from chemical-resistant polypropylene (PP), this stopcock features 4" BSP female threads (≈ 114.3 mm major diameter) on both inlet and outlet ends, ensuring seamless integration with standard threaded piping systems. The PP body remains lightweight yet exceptionally strong, offering superior resistance to corrosion, UV exposure and aggressive chemicals commonly found in industrial and outdoor applications.

At its core lies a precision-engineered stainless-steel ball that prevents corrosion and delivers smooth, wear-resistant operation under pressure, reducing maintenance over thousands of cycles. The ball is actuated by a rubberised lever handle—available in red or blue—for an ergonomic, slip-resistant grip and clear visual indication of open or closed position.

The BSP female threads are moulded to tight tolerances for a reliable, leak-proof seal. Polypropylene construction also withstands temperature fluctuations and resists scale build-up, making this stopcock ideal for demanding industrial, commercial or residential fluid-control applications where durability and longevity are essential.
