Description
Pneumatic Push-Fit Fittings — Professional Grade
R1/4 BSP Male Stud Coupling
to 12mm Push-Fit Tube
Precision-engineered in nickel-plated CW617N brass. Instant tool-free tube insertion, zero-leak BSP thread engagement — built for continuous industrial and workshop duty.
Overview
The R1/4 BSP Male Stud Coupling to 12mm is the definitive push-fit connector for engineers who refuse to compromise. Machined from CW617N free-cutting brass and finished with a corrosion-resistant nickel plate, this fitting delivers a leak-free, vibration-resistant seal the moment tube is inserted — no tools, no clamps, no secondary operations. Whether you are plumbing a production-line manifold, a workshop compressor circuit, or a precision automation cell, this coupling performs without hesitation, shift after shift.
Technical Specifications
Why This Fitting
Instant Push-Fit Connection
Insert tube to full depth and the internal collet grips immediately — no spanners, no ferrules, no waiting. Disconnect in seconds by depressing the release collar.
Zero-Leak BSP Thread Seal
The precision-machined R1/4 BSP parallel thread mates flush with standard port faces. Combined with the NBR O-ring, it eliminates the need for PTFE tape on parallel-ported manifolds.
Industrial-Grade Brass Construction
CW617N free-cutting brass offers superior machinability and corrosion resistance. The nickel plate adds a further barrier against oxidation in humid workshop environments.
Certified & Compliant
ISO 228-1 thread form, RoHS-compliant materials, and CE marking ensure this fitting meets the regulatory requirements of UK and EU industrial installations.
Compatible Tube Types
- Polyurethane (PU) pneumatic tube — 12mm OD
- Nylon (PA) pneumatic tube — 12mm OD
- Polyethylene (PE) pneumatic tube — 12mm OD
- Semi-rigid and flexible air line hose — 12mm OD
Installation Guide
Frequently Asked Questions
Is this fitting suitable for compressed air systems?
Yes. It is rated for compressed air and inert gases at 0–10 bar (145 PSI) across a temperature range of −20°C to +80°C, covering the full operating envelope of standard workshop and industrial compressor systems.
Do I need PTFE tape on the BSP thread?
For parallel (BSPP) ports with a machined face, the integrated NBR O-ring provides the primary seal — PTFE tape is not required. For tapered BSP ports, apply PTFE tape or anaerobic thread sealant as standard practice.
Can I reuse this fitting after removing the tube?
Yes. The push-fit collet mechanism is designed for repeated insertion and removal cycles without loss of sealing performance, provided the tube end remains undamaged and clean.
What tube outside diameter does this accept?
This fitting accepts 12mm outside diameter (OD) tube only. Ensure your tube is measured by OD, not bore (ID), before ordering.
