Are you looking for superior quality Brass Compression Fitting Tee exporter and suppliers? Quick delivery and dispatch available with certified mill test reports.
Buy best price high-quality, corrosion resistant Brass Compression Fitting Tee, Brass Compression Tube Fittings from Pioneer Industries recognized for manufacturing quality-tested products using latest manufacturing equipment at International Industry standards.
At Pioneer Industries, we offer these Industrial Brass Compression Fitting Tee with utmost functionality for your required applications. We are manufacturer, supplier of Brass Compression Fitting Tee and India’s leading Brass Compression Fittings Exporters in Mumbai.
Compression fittings function by the compression of an ‘olive’ between two tapered surfaces and the pipe itself. The two surfaces are the body of the fitting (beveled seat) and the compression nut. As the nut is tightened, the olive is compressed onto the pipe, creating an airtight, watertight, zero-leak seal.
We are India’s one of the leading Brass Compression Fitting Tee manufacturers and exporters to more than 85 countries for exporting and manufacturing on a large scale. All size supply maintains a massive inventory of Brass Compression Fitting Tee, with all standard sizes and numerous styles available.

Pioneer Industries’ Brass Compression Fitting Tee are widely used in numerous industries like:
Expert engineering insights and technical guidance regarding design specifications, pressure tolerances, olive swaging mechanics, tubing compatibility, and installation best practices for industrial Brass Compression Fitting Union Tee.
A Brass Compression Fitting Tee (also known as an Equal Tube Union Tee) is a three-way tube fitting featuring compression tube connections on all three ports. It is installed to split an incoming supply tubing line into two separate paths, or to combine two return lines into a single discharge line without requiring soldering or tube flaring.
Operating pressure ratings range from 400 PSI (28 bar) for 1/8″ and 3/16″ tube sizes, 300 PSI (21 bar) for 1/4″ and 5/16″, 250 PSI for 3/8″, 200 PSI for 1/2″, 150 PSI for 5/8″, down to 100 PSI for 3/4″ tubing, backed by an engineered 4:1 safety factor per ASME B31.3.
Pioneer tee bodies are hot-forged from BS 218 / CW617N brass blanks under high hydraulic pressure. This refines the alloy's crystalline grain structure along all three fluid passages, providing over 80% higher tensile strength than cast brass and completely eliminating porosity, micro-voids, and leak paths.
Seamless copper, brass, and aluminum tubing are compatible directly. For polymer tubing (nylon, polyurethane, polyethylene), an internal brass tube support insert must be used to prevent wall collapse during olive swaging.
Yes. Pioneer manufactures Brass Reducing Compression Tees (e.g. 3/8″ run x 1/4″ branch) where the branch or run port is smaller, enabling tube size transitions without extra reducing adapters.
Deburr the square-cut tubes, slide the nut and olive onto each tube, insert into the fitting until bottomed against the internal shoulder, finger-tighten the nuts, and tighten 1-1/4 turns past finger tight with an open-end wrench while holding the forged body flats.
Yes. The compression nuts can be disconnected for line servicing and retightened without replacing the pre-swaged tube and olive. Tighten finger-tight plus 1/4 to 1/3 turn with a wrench during remakes.
Yes. They are widely used in pneumatic control headers, HVAC-R refrigerant sensing circuits, and machine tool lubrication distribution due to their hermetic metal-to-metal seal and non-sparking characteristics.
Options include natural bright brass, electrolytic bright nickel plating (5–8 µm) for cosmetic brilliance, and electroless nickel plating (ENP, 10–25 µm) for severe chemical and marine environments.
Every batch is verified with thread pitch gauges, tested for pressure integrity at 100 PSI bubble leak immersion, and supplied with authentic EN 10204 Type 3.1 Mill Test Certificates.
