Description
3/8" BSP Female Quick Release Air Line Coupling — High Flow Steel
SKU: COUP-F38-HF-QR · Rp 3/8" Female Thread · 43 CFM @ 100 PSI
The Airflow Series 3/8" BSP Female Quick Release Coupling is engineered for professionals who demand zero compromise in their compressed air systems. Built from high-grade steel with a precision-machined Rp 3/8" female thread, this coupling delivers an instantaneous, leak-free connection — and an equally clean one-handed release — without interrupting workflow. At 43 CFM flow capacity and a 14 bar working pressure rating, it is equally at home driving impact wrenches in a busy automotive workshop as it is powering spray guns in a finishing bay.
High Flow Design
43 CFM at 100 PSI ensures maximum air delivery to hungry tools — no throttling, no pressure drop.
14 Bar Pressure Rating
Rated to 200 PSI — well above typical workshop compressor output — for a wide safety margin.
One-Hand Connect & Release
Precision-engineered locking sleeve engages and releases with a single hand — essential in busy workshop environments.
Extreme Temperature Tolerance
Operates reliably from −40°C to +100°C — suitable for cold stores, outdoor use, and high-heat industrial environments.
Steel Construction
Robust steel body resists impact, corrosion, and the daily abuse of professional workshop use — built to outlast cheaper alternatives.
Rp 3/8" Parallel Thread
Rp (parallel internal) thread form provides a reliable, repeatable seal — compatible with the vast majority of UK and European pneumatic fittings.
This coupling uses an Rp 3/8" BSP parallel internal thread. It is designed to mate with male connectors, hose tails, and airline fittings carrying an R 3/8" (BSPT) or Rp 3/8" (BSPP) male thread. Always verify thread form before installation — BSP parallel and tapered threads are not interchangeable without appropriate sealant or adapters.
