Description
Overview:
The PCL Instantair Coupling Male Thread G 1/4" (AC51CM) is a robust compressed-air coupling for workshop, site, and garden machinery use. Built from durable metal with a corrosion-resistant finish, it provides a reliable interface between air lines and tools while maintaining consistent airflow. The male thread is G 1/4" (BSPP), with an approximate major diameter of 13.2 mm, making it a common fit on regulators, manifolds, and tool inlets. A compact hex body aids secure tightening with a spanner, helping achieve a leak-resistant seal when used with the correct sealing method for your system. Suitable for compressors, hoses, and pneumatic tools such as nailers, impact wrenches, and inflators, the AC51CM is a practical choice for tradespeople and DIY users who need dependable, repeatable connections.
Key Features:
- Durable metal construction for long service life in workshop and site environments
- G 1/4" BSPP male thread (approx 13.2 mm major diameter) for broad system compatibility
- Precision-machined coupling for a secure, leak-resistant connection and steady airflow
- Compact hex body for easy installation with standard spanners
- Corrosion-resistant finish suited to everyday workshop conditions
- Smooth internal bore to support efficient air delivery to tools and equipment
- Compatible with common compressed-air setups using G 1/4" ports on hoses, regulators, and manifolds
- Straightforward to fit; use appropriate sealing method (e.g. washer or suitable thread sealant) as required by your system
Typical Applications:
Connecting air lines to tools, filters, regulators, and manifolds on compressors, site equipment, and workshop systems. Common in construction, automotive, and garden machinery maintenance where reliable, quick coupling and uncoupling of air tools and hoses is required.
Also known as:
BSPP 1/4" male airline coupling, G1/4M pneumatic coupling, 1/4 BSP male air connector, compressed-air coupling, male threaded air hose fitting, pneumatic male adaptor.
