Pioneer Industries manufactures precision Brass Push to Lock Union Y fittings engineered for smooth, streamlined 2-way pneumatic tube branching. Features three one-touch push-in sockets (one supply inlet and two diverging outlet branches), 304 stainless steel collets, and electroless nickel plating.
The Brass Push to Lock Union Y (3-port equal push-in Y splitter) manufactured by Pioneer Industries is a specialized pneumatic distribution fitting designed to split a single incoming tube line into two parallel or diverging lines with minimal flow resistance. With its acute-angle internal flow path, it provides significantly higher flow coefficients (Cv) and reduced turbulence compared to standard 90-degree tees.
Precision-machined and hot-forged from extruded brass IS 319 / CW614N and plated with electroless nickel, the union Y incorporates three identical push-to-lock sockets. Each port features an independent 304 stainless steel collet and Nitrile O-ring, delivering bubble-tight retention from -750 mmHg vacuum up to 16 Bar operating pressure.
Pioneer Industries manufactures and exports Brass Push to Lock Union Y fittings to leading industrial equipment builders, robotics manufacturers, automotive assembly plants, and packaging OEMs in more than 85 countries worldwide. Operating from our Mumbai production hub, we maintain comprehensive ready stock across all metric tube sizes.
Every production lot undergoes 100% pneumatic bubble immersion testing at 10 Bar to verify zero defect seal integrity. Consignments are accompanied by authentic EN 10204 Type 3.1 Material Test Certificates, CMM dimensional verification records, and RoHS compliance declarations.

Engineered for continuous duty in demanding automation environments, the Pioneer Brass Push to Lock Union Y delivers superior mechanical durability compared to standard plastic push-in unions. Its solid all-metal body resists high-impact shop floor collisions, weld spatter, airborne abrasives, and aggressive synthetic compressor lubricants.
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 Union Y fittings in metric tube sizes 4 mm, 6 mm, 8 mm, 10 mm, and 12 mm OD (Codes P0404 to P0412). Certified under ISO 14743 and ASME B31.3 with a 4:1 safety burst factor.

Expert engineering insights and technical guidance regarding flow dynamics, pressure thresholds, tubing compatibility, and installation protocols for Brass Push to Lock Union Y.
A Brass Push to Lock Union Y is a 3-port push-in fitting with one inlet and two diverging outlets at an acute angle. Its streamlined geometry produces less turbulence, lower pressure drop, and higher volumetric flow (Cv) than a 90-degree tee.
Certified for positive working pressures up to 16 Bar (230 PSI / 1.6 MPa) with proof pressure exceeding 35 Bar, and industrial vacuum down to -750 mmHg (-29.5 inHg).
Compatible with standard metric Nylon (PA6, PA11, PA12), Polyurethane (PU 95A/98A), Polyethylene, and Fluoropolymer (PTFE/FEP) lines.
Push the 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: P0404 (4mm), P0406 (6mm), P0408 (8mm), P0410 (10mm), and P0412 (12mm) Tube O.D.
Yes. Each of the three ports features its own independent release collar and 304 stainless steel collet. Any single tube can be disconnected and reconnected freely.
All-metal brass union Y fittings provide superior crush strength, will not crack under machine vibration or tool impact, and resist high ambient temperatures and aggressive compressor oils.
Standard Nitrile (NBR) seals operate between -20°C and +80°C (-4°F to +176°F). Optional Viton (FKM) seals are available for up to +150°C.
Yes. The symmetrical internal diverter chamber ensures perfectly equal flow distribution and pressure balance between the two diverging output ports.
