Description

Pneumatic Fittings — Professional Grade

Brass Straight Stud Coupling
R 1/4" Male Thread × 6mm Push-Fit Tube

Precision-machined from solid brass. Engineered for compressed air systems that demand a leak-proof, tool-free connection — rated to 16 bar for continuous industrial duty.

16 Bar / 232 PSI BSPT R 1/4" 6mm OD Tube UK Stock Trade Ready
Overview

The definitive push-fit stud coupling for professional pneumatic installations. Where reliability is non-negotiable and downtime is not an option.

This straight male stud push-fit connector bridges a 6mm OD pneumatic tube to an R 1/4" (BSPT) male threaded port with a single, confident push. The collet-and-O-ring mechanism locks the tube instantly — no tools, no PTFE tape on the tube side, no second-guessing the seal. Machined from high-grade brass with a corrosion-resistant finish, this fitting is built to perform across automotive workshops, marine engineering bays, industrial automation rigs, and compressed air distribution networks.

Engineering Highlights
Instant Push-Fit
Tool-free tube insertion and secure collet lock. Tube releases cleanly by depressing the collet ring.
16 Bar Rated
Certified to 16 bar (232 psi) working pressure — suitable for the full range of industrial compressor outputs.
Solid Brass Body
Precision-machined brass resists corrosion, handles vibration, and maintains dimensional integrity over years of service.
BSPT R 1/4" Thread
Standard British Standard Pipe Taper thread — compatible with the vast majority of UK and European compressor ports.
Wide Temperature Range
Operates reliably from −20°C to +80°C — unaffected by cold workshop starts or heated industrial environments.
Compact Profile
Straight stud geometry minimises protrusion — ideal for panel-mount ports and space-constrained manifold assemblies.

Frequently Asked Questions
Is this fitting compatible with standard UK air compressor ports?
Yes. The R 1/4" BSPT male thread is the most common port size on UK and European compressors, regulators, and manifolds. It will thread directly into any female R 1/4" BSP port without adapters.
What tube type is compatible with the push-fit end?
The push-fit collet accepts 6mm outside diameter (OD) pneumatic tubing — typically nylon (PA), polyurethane (PU), or polyethylene (PE) tube. Ensure the tube end is cut cleanly and squarely for a reliable seal.
Do I need PTFE tape on the thread?
Yes — apply 2–3 wraps of PTFE tape to the male thread before installation to ensure a leak-free seal at the threaded port. The push-fit tube side requires no sealant.
Can this fitting be used with gases other than air?
This fitting is rated for compressed air and inert gases. It is not suitable for flammable gases, hydraulic fluids, or aggressive chemicals. Consult our team for specialist media applications.
