The Olive Union Only BSP is a precision brass fitting designed to join tubes or pipes with a secure compression seal using the British Standard Pipe (BSP) threading. It enables a reliable connection without welding or soldering, ideal in applications involving gas, water, air lines, or hydraulic systems. Its compact design includes a nut and olive (ferrule) that compresses onto tubing for a leak-proof joint. Due to its high material strength and corrosion resistance, this union fitting provides durable performance even under pressure or fluctuating temperatures. Easy to install and maintain, it’s suited for both professional plumbing systems and industrial installations.
