Pioneer Industries manufactures heavy-duty Brass Push to Lock Female Elbows engineered for compact 90-degree right-angle transitions from metric tubing into male threaded ports. Features an instant one-touch tube socket, precision female BSPP/NPT pipe threads, and electroless nickel plating for industrial automation.
The Brass Push to Lock Female Elbow (90-degree female elbow adapter) manufactured by Pioneer Industries is a specialized directional fitting designed to route pneumatic tubing at a right angle directly into male pipe nipples, sensor ports, or equipment stems. It eliminates the need for separate street elbows and female couplings, saving valuable space in dense machine enclosures.
Hot-forged and precision-machined from extruded brass IS 319 / CW614N and plated with electroless nickel, the elbow features a one-touch push-in socket on one leg and a parallel (BSPP/G per ISO 228) or tapered (NPT per ASME B1.20.1) female threaded port on the other. An internal 304 stainless steel collet and Nitrile O-ring deliver instant, tool-free tube retention with bubble-tight integrity up to 16 Bar pressure and vacuum down to -750 mmHg.
Pioneer Industries manufactures and exports Brass Push to Lock Female Elbows to global automation OEMs, robotic fixture builders, and pneumatic system designers across more than 85 countries. Headquartered in Mumbai, India, our production lines maintain continuous ready stock of metric tube sizes from 4mm to 12mm for rapid worldwide delivery.
Every female elbow is 100% pneumatic bubble tested at 10 Bar pressure to guarantee zero leak defects. Deliveries include authentic EN 10204 Type 3.1 Material Test Certificates, dimensional CMM verification reports, and RoHS compliance certificates.

Engineered for high-vibration machinery and severe fluid pulsations, the Pioneer Brass Push to Lock Female Elbow features a solid forged brass body that provides superior mechanical strength compared to plastic elbows. Its precision-machined wrench flats allow accurate torque application without slipping or distorting the fitting.
Connecting tubing requires zero tools: simply push the cut tube firmly into the socket past the internal O-ring stop. Disconnecting is accomplished in seconds by depressing the circular release collar, smoothly releasing the stainless steel collet teeth without scratching or damaging the tubing outer diameter.
Pioneer Industries manufactures Brass Push to Lock Female Elbows in metric tube sizes 4 mm to 12 mm OD with 1/8" to 1/2" female threads (Codes P1604 to P4612). Certified under ISO 14743 and ASME B31.3 standards.

Expert engineering insights and technical guidance regarding flow dynamics, pressure thresholds, tubing compatibility, and installation protocols for Brass Push to Lock Female Elbow.
A Brass Push to Lock Female Elbow is a 90-degree adapter with a push-to-lock tube port on one side and a female pipe thread on the other. It is used to connect tubing at a right angle directly to male threaded pipe stems or equipment ports without extra adapters.
Standard threads include parallel BSPP/G (ISO 228) and tapered NPT (ANSI/ASME B1.20.1) in sizes 1/8", 1/4", 3/8", and 1/2".
The fitting is rated for positive working pressures up to 16 Bar (230 PSI / 1.6 MPa) and vacuum down to -750 mmHg (-29.5 inHg).
For tapered NPT threads, apply PTFE thread tape or liquid anaerobic sealant. For parallel BSPP female threads, use a suitable bonded sealing washer or O-ring against the male shoulder.
The tube can swivel within the internal collet around its axis before line pressurization, allowing easy orientation of the tubing run.
The series accommodates metric tube sizes 4mm, 6mm, 8mm, 10mm, and 12mm Tube Outer Diameter.
Operating temperature spans from -20°C to +80°C with standard NBR O-rings, and up to +150°C with optional Viton (FKM) seals.
Fully compatible with Nylon (PA6, PA11, PA12), Polyurethane (PU 95A/98A), Polyethylene, and Fluoropolymer (PTFE/FEP) lines.
Yes. The hot-forged brass body and spring-tempered 304 stainless steel gripping teeth are engineered specifically to isolate machine vibration and prevent tube pull-out.
