Pioneer Industries manufactures precision Brass Push to Lock Tees engineered for balanced 3-way pneumatic tube-to-tube branching. Features three equal one-touch push-in sockets at 90-degree orthogonal orientations, 304 stainless steel collets, and electroless nickel plating for industrial automation.
The Brass Push to Lock Tee (3-way equal union tee) manufactured by Pioneer Industries is an essential pneumatic distribution fitting designed to split a single incoming tube line into two perpendicular runs, or merge two distinct lines into a single stream. Engineered with three identical push-to-lock sockets, it enables fast, tool-free tubing branches across automated machines.
Hot-forged from high-tensile brass IS 319 / CW614N and plated with electroless nickel, the tee features two inline run ports and one central 90-degree branch port. Each port incorporates an independent 304 stainless steel gripping collet and a precision 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 Tee 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 Tee 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 Tees in metric tube sizes 4 mm, 6 mm, 8 mm, 10 mm, and 12 mm OD (Codes P0204 to P0212). 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 Tee.
A Brass Push to Lock Tee is a 3-port pneumatic union with two inline ports and one 90-degree branch port, all designed for push-in tubing of the same outer diameter. It is used to split or combine pneumatic fluid lines without threading.
The fitting is certified for positive operating 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: P0204 (4mm), P0206 (6mm), P0208 (8mm), P0210 (10mm), and P0212 (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 tees provide superior crush strength, will not crack when stepped on or bumped, 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.
The precision-machined internal chamber ensures smooth fluid transition and minimal pressure drop between the inline run and perpendicular branch.
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.
