Engineering Advantages
Why Professionals Specify This Fitting
Maximum Airflow
Large-aperture 10.3 mm bore minimises pressure drop, delivering 117 CFM at 100 PSI for the most demanding air tools.
Case-Hardened Durability
Sheffield-grade case-hardened steel with corrosion-resistant finish resists wear, impact, and chemical exposure in harsh workshop environments.
Universal Compatibility
RP 3/8" BSP parallel thread integrates with all major UK and European pneumatic systems, compressors, and tool inlets without adaption.
Extreme Temperature Range
Rated from −40°C to +100°C — performs reliably in cold-store facilities, outdoor plant, and high-temperature production environments.
Ideal For
Professional Applications

- 100 Series couplings, connectors, and manifolds
- Standard RP 3/8" male threaded fittings from all major manufacturers
- Air compressor outlets, receiver tanks, and distribution manifolds
- Pneumatic tool inlets, hose assemblies, and regulator ports
- All major air compressor brands operating on BSP parallel thread systems
Since
1938
Sheffield Engineering Excellence. Manufactured to exacting British engineering standards since 1938, every 100 Series adaptor undergoes rigorous quality control before leaving Sheffield — because in professional environments, component failure is not an option. This is not a compromise fitting. It is a professional-grade component built for workshops where downtime costs money.
