This female brass stem adaptor is designed to convert a John Guest push-fit connection to a female BSP threaded outlet, making it ideal for creating swivel-type connections within compressed air and pneumatic systems. It is commonly used where flexibility and secure threaded joints are required at connection points.

The push-fit stem allows fast, tool-free installation, while the precision-engineered collet locking system grips the pipe securely without deformation or flow restriction. An integrated nitrile O-ring provides a dependable, airtight seal to maintain system integrity.

Manufactured from durable, corrosion-resistant brass, the adaptor is fully demountable, allowing systems to be easily modified or maintained with minimal downtime. Its broad compatibility makes it suitable for use with a wide range of plastic and soft metal pipe materials across industrial, workshop and commercial environments.
