black push-fit acetal female adaptor (BSP thread) fitting connects metric sized pipework to a BSP type fitting. Fast and simple to install, push-fit fittings create an instant push-fit connection and leak tight seal without the need for tools, hot works or sealing agents. The unique collet locking design firmly and securely holds the pipe in place without deforming the pipe or restricting flow. Fittings are corrosion resistant and fully demountable, improving system performance and reducing system downtime during maintenance. Manufactured in acetal copolymer, the fitting is suitable for water, potable liquids and intermittent hot water applications (up to 65C max). All fittings are manufactured and assembled in the UK.
