Pioneer Industries manufactures precision Brass Push to Lock Elbow fittings engineered for tight 90-degree directional changes in pneumatic tubing runs. Features dual one-touch push-in sockets, 304 stainless steel gripping collets, and electroless nickel plating for smooth, low-turbulence fluid routing.
The Brass Push to Lock Elbow (90-degree equal union elbow) manufactured by Pioneer Industries is an essential directional fitting designed to route pneumatic tubing around tight structural corners, machine frames, and enclosure partitions. By establishing a fixed 90-degree bend, it eliminates excessive tube kinking, radial wall collapse, and flow restriction in high-density automation systems.
Hot-forged and precision-machined from extruded brass alloy IS 319 / CW614N and coated with electroless nickel, the elbow features two orthogonal push-in sockets. Each port contains a multi-tooth 304 stainless steel collet and high-density Nitrile O-ring, delivering instant tool-free tube retention and leak-tight performance from -750 mmHg vacuum up to 16 Bar pressure.
Pioneer Industries manufactures and exports Brass Push to Lock Elbow fittings to leading industrial OEMs, robotic integrators, automotive plants, and packaging machine manufacturers in more than 85 countries worldwide. Operating from our Mumbai production facility, we maintain large-scale stock of all metric sizes for prompt global shipping.
Every production lot undergoes 100% pneumatic bubble leak testing at 10 Bar. Deliveries are accompanied by authentic EN 10204 Type 3.1 Material Test Certificates, dimensional inspection reports, and RoHS compliance documentation.

Engineered to withstand rigorous mechanical demands, the Pioneer Brass Push to Lock Elbow provides outstanding crush strength and structural rigidity. Unlike commercial plastic elbows that crack under vibrational stress or incidental tool impact, our forged brass body ensures long-term operational security in heavy-duty factory environments.
Tubing connects with a single smooth push past the internal O-ring stop, achieving a bubble-tight seal without tools. Depressing the nickel-plated release collar disengages the collet instantly, allowing tubing to be withdrawn unblemished and reused repeatedly during maintenance overhauls.
Pioneer Industries manufactures Brass Push to Lock Elbows in metric tube sizes 4 mm, 6 mm, 8 mm, 10 mm, and 12 mm OD (Codes P0104 to P0112). Compliant with 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 Elbow.
A Brass Push to Lock Elbow is a 90-degree equal union fitting that joins two tubes of identical outer diameter at a right angle. It prevents tubing from exceeding its minimum bend radius, eliminating flow-restricting kinks and premature fatigue fractures.
The fitting is certified for positive operating pressures up to 16 Bar (230 PSI / 1.6 MPa) with a burst threshold exceeding 35 Bar, and handles industrial vacuum down to -750 mmHg (-29.5 inHg / 10 Torr).
Compatible tubing includes Nylon (PA6, PA11, PA12), Polyurethane (PU 95A/98A), Polyethylene (LDPE/HDPE), and Fluoropolymer (PTFE, FEP, PFA) lines.
Push the square-cut tube firmly into the socket until it bottoms against the internal stop. To release, depressurize the system, press the release collar inward, and withdraw the tube smoothly.
Pioneer Industries manufactures standard sizes: P0104 (4mm), P0106 (6mm), P0108 (8mm), P0110 (10mm), and P0112 (12mm) Tube O.D.
90-degree directional changes experience dynamic fluid momentum shock and mechanical pull forces. Forged brass prevents elbow cracking, thread deformation, and stress fractures common in plastic fittings.
Equipped with high-density NBR O-rings, the standard operating envelope is -20°C to +80°C. Optional Viton (FKM) O-rings extend the thermal rating up to +150°C.
The union elbow allows the tube to swivel freely around its longitudinal axis inside the collet before pressure is applied, facilitating easy alignment during assembly.
The internal radius is precision-contoured to minimize turbulent eddy currents, delivering maximum flow coefficient (Cv) with negligible pressure drop.
Consignments are backed by ISO 9001:2015 certification, 100% pneumatic bubble leak testing, RoHS compliance documents, and authentic EN 10204 Type 3.1 Mill Test Certificates.
