Product Number: AC21EF
Supplied as a pack of 2: two identical PCL AC21EF couplings, so you can fit one at each airline outlet or keep a spare ready for when one wears.
Incompatible or worn airline fittings cause pressure loss and slow down workshop productivity. The PCL AC21EF is a quick-release coupling in the Airflow series, female thread, Rp 3/8, manufactured in Sheffield and part of a design lineage dating back to 1938.
The Airflow range delivers a 4.8 mm bore with a rated flow of 43 cfm at 100 psi, making it well suited to high-demand compressed-air applications where consistent flow matters. Maximum working pressure is 14 bar (200 psi), and the operating temperature range spans -40°C to 100°C, covering most workshop and industrial environments. The coupling is interchangeable with Cejn 295 and Rectus 19 series fittings, which broadens its compatibility across mixed-brand airline systems.
The female Rp 3/8 thread designation means the AC21EF accepts a male Rp 3/8 threaded fitting or adaptor. As part of the Airflow series, this coupling is offered alongside male-thread and hose-tail variants in multiple thread sizes, allowing a consistent and leak-resistant airline system to be assembled from a single product family.
Manufactured in Sheffield, UK, by PCL — part of HORNGROUP — since 1938. No box contents or warranty terms are specified in the available source data.
