Description
100 Series · Pneumatic Fittings · Air Compressors UK
The Rp 3/8" Female Thread Adaptor
Built for Compressed Air That Cannot Fail
Precision-machined from high-grade steel, this 100 Series adaptor delivers a leak-free, high-flow connection between your air line and pneumatic tooling — rated to 14 bar / 200 psi and engineered for continuous industrial duty.
Product Overview
The 100 Series Rp 3/8" Female Thread Adaptor is the professional's choice for connecting compressed air hoses, couplings, and pneumatic tools to workshop air lines. Its precision-machined steel body ensures dimensional accuracy and long-term sealing integrity — even under the thermal cycling and vibration loads common in automotive, manufacturing, and industrial environments.
With a nominal bore of 10.3 mm and a maximum flow rate of 117 cfm at 100 psi, this adaptor will not become the bottleneck in your air system. It threads directly onto Rp 3/8" (parallel female) ports and mates with the full 100 Series quick-connect range for tool-free coupling and decoupling under pressure.
Engineering Highlights
High-Grade Steel Body
Resists deformation, corrosion, and mechanical shock in demanding workshop and industrial environments.
14 Bar / 200 psi Rated
Exceeds the working pressure of most workshop compressors, providing a substantial safety margin.
117 cfm @ 100 psi Flow
Unrestricted airflow ensures full tool performance — no pressure drop, no productivity loss.
Wide Temperature Range
Operates reliably from -40°C to +100°C — suitable for cold stores, outdoor plant, and heated production lines.
Rp 3/8" Parallel Thread
Rp (parallel internal) thread provides a consistent, repeatable seal without thread deformation over multiple assemblies.
100 Series Compatible
Integrates seamlessly with the full Air Compressors UK 100 Series coupling and plug range for a unified system.
