Product Number: AC21JM
Quick-release airline couplings with a mismatched thread or incompatible profile cause air leaks and slow down workshop operations. The PCL AC21JM is a male-thread quick-release coupling in the Airflow series, sized R 1/2, manufactured in Sheffield as part of the HORNGROUP. The Airflow series carries the British Standard profile and is designed for fixed applications — particularly over a workbench — where a single-action release is preferred. Each coupling is constructed from steel for robustness in engineering and workshop environments, features a positive locking mechanism, and carries a blue PCL silicone band for identification, protection, and ease of use. Date stamping on each unit supports traceability and quality performance. The AC21JM is compatible with Standard Adaptors and carries the series ratings of the Airflow range: nominal bore 4.8 mm, flow rate 43 cfm at 100 psi, maximum working pressure 14 bar (200 psi), and an operating temperature range of -40°C to 100°C. The platform lists the nominal bore as 5 mm; the brand catalogue value is 4.8 mm. Interchange compatibility for the Airflow series includes Cejn 295 and Rectus 19 profiles; the platform additionally lists Kee 057 Series, OETIKER SC Series P, and Ludecke ESB.
