02 — Product Detail

Description of Brass PU Male Connector

Brass PU Male Connector is a precision-engineered pneumatic fitting designed to provide instant, tool-free push-to-lock tubing connections across industrial pneumatic, robotics, automation, and instrumentation fluid systems.

Constructed with a heavy-duty extruded or forged brass body, internal stainless steel gripping collets, and elastomeric O-rings, the fitting delivers high mechanical impact strength, vibration resistance, and positive airtight sealing under continuous line pulsing, vacuum service, and operating pressures up to 15 bar.

Features Brass PU Male Connector:

  • Extreme conditions durability: Precision designed to withstand high pressure, mechanical shock, vibration, vacuum, and temperature fluctuations.
  • Instant tool-free assembly: Push-to-lock connection allows immediate tube insertion and rapid one-touch disconnection without specialized tools.
  • High-grade brass body: Machined from solid forged / extruded brass (CW614N / IS 319) with high tensile strength and impact resistance.
  • Stainless steel gripping collet: Spring-tempered AISI 301/304 gripping teeth hold calibrated PU and nylon tubing securely without pull-out.
  • Leak-tight elastomeric sealing: Internal NBR / FKM O-rings deliver 100% airtight sealing under full working pressure and vacuum.
  • Bright nickel-plated finish: Highly resistant to atmospheric corrosion, oil exposure, moisture, and harsh industrial environments.
  • Superior 4:1 safety factor: Engineered with a 4:1 design factor ensuring tubing burst protection before joint failure.

Frequently Asked Questions about Brass PU Male Connector

Comprehensive technical guidance and engineering answers regarding Brass PU Male Connector, push-in collet mechanics, pressure containment, and pneumatic specifications from Pioneer Industries.

A Brass PU Male Connector (also known as a Brass Push-in Male Stud or Male Straight Fitting) is the foundational pneumatic fitting that connects calibrated polymer tubing directly into female-threaded equipment ports. It features an in-line push-to-lock tube port on one end and an external male pipe thread (NPT, BSPT, BSPP, or Metric) on the other.
Pioneer supplies male threads conforming to: (1) NPT (ANSI/ASME B1.20.1) tapered pipe threads for US and offshore equipment; (2) BSPT / R (ISO 7/1) tapered threads with optional pre-applied PTFE thread sealant; (3) BSPP / G (ISO 228) parallel threads with an integrated elastomeric O-ring or captive washer; (4) Metric ISO fine threads (M5 to M20) with captive sealing gaskets.
Available in metric tube OD sizes of 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, and 16 mm, as well as fractional imperial sizes from 1/8″, 5/32″, 1/4″, 5/16″, 3/8″, to 1/2″ OD paired with thread sizes from M5 to 1/2″ NPT/BSPP.
Vacuum (-0.99 bar / -100 kPa) up to 15 bar (220 PSI) working pressure, 25 bar proof pressure, and a 4:1 burst safety factor. Temperature ranges from -20°C to +80°C (standard NBR) or -20°C to +150°C (optional FKM/Viton).
Yes. In addition to external body wrench flats, compact Pioneer Male Connectors feature an internal hexagonal socket (Allen key drive) machined through the center tube port, enabling rapid tightening in high-density multi-valve manifold blocks where standard spanners cannot fit.
Plastic male threaded connectors frequently snap off at the thread neck under line vibration or slight over-torqueing, leaving broken threads stuck inside expensive valve bodies. Pioneer's solid brass CW614N body withstands extreme torque, impact, and fatigue.
An internal spring-tempered AISI 301/304 stainless steel gripping collet bites into the tube OD when pushed in, while an internal O-ring establishes an immediate airtight perimeter seal. Pushing the release sleeve allows instantaneous, non-destructive tube removal.
Standard electrolytic bright nickel plating (5–8 µm) provides superior oxidation protection, scratch resistance, and an attractive industrial appearance. Electroless nickel and natural brass are also available.
Polyurethane (PU/TPU), nylon (PA6, PA11, PA12), polyethylene (PE), and fluoropolymer (PTFE/FEP) tubing conforming to ISO 14743 tolerances.
Every production batch undergoes 100% pneumatic bubble immersion testing at 10 bar, optical thread inspection, and is delivered with authentic EN 10204 Type 3.1 inspection certificates.
