Product Number: AC21EM
Worn or incompatible airline fittings cause pressure loss and disrupt workshop airflow. The PCL AC21EM is a male-thread quick-release coupling with an R 3/8 (BSP taper) thread, part of the Airflow series — manufactured in Sheffield since 1938 and designed for reliable compressed-air line connections across professional workshop and industrial environments.
As a member of the Airflow series, the AC21EM shares the series-rated specification that underpins the range: a 4.8 mm bore, a flow rate of 43 cfm at 100 psi, a maximum working pressure of 14 bar (200 psi), and an operating temperature range of -40°C to 100°C. The series is compatible with Cejn 295 and Rectus 19 interchange standards, broadening its fit across mixed-fitting installations. These are series-level ratings applicable across the Airflow range.
The R 3/8 male thread suits a wide variety of airline hose tails, compressor outlets, and tool inlets where a BSP taper connection is required. PCL have been producing quick-release couplings in Sheffield since 1938, and the Airflow range reflects that accumulated engineering experience. The AC21EM is part of HORNGROUP.
