Tube Fittings Standard

Tube Fittings Standard

PISCO’s Standard Tube Fittings is a premier line of quick-connect, push-in joints engineered for general-purpose pneumatic piping and fluid systems. Known for their tool-free connection mechanism, these fittings automatically grip and seal pneumatic tubing (such as polyurethane or nylon) simply by pushing the tube into the port.

Standard Push-In Fittings are available in a wide range of models to suit diverse pneumatic piping needs. Water use is permitted under specified conditions (excluding space-saving type).

Ardee Hi-Tech Pvt. Ltd. is the official and authorized distributor of PISCO Standard Push-In Pneumatic Fittings in India.

General Specifications

General Specifications & Operating Limits

  • Fluid Media: Compressed Air and Industrial Water (subject to conditional parameters).
  • Maximum Operating Pressure: 1.0 MPa (145 psi / 10 bar).
  • Maximum Operating Vacuum: -100 kPa (-29.5 in. Hg / -1 bar).
  • Operating Temperature Range: 0 to 60°C (32 to 140°F) strictly with no freezing conditions.
  • Water Application Requirements: Tap water is permitted provided surge pressures remain strictly below 1.0 MPa. A dedicated Pisco Insert Ring must be placed into the tube edge to ensure connection integrity.

Advanced System Features & Packaging Options

  • 360° Rotatable Body: The composite resin body can change orientation and rotate freely even after the threaded stud section is fixed in position.
  • Pre-Coated Thread Sealant: Tapered R threads feature factory-applied Sealock coating, eliminating the application of Teflon tape and reducing setup times.
  • Clean-Room Package Options: Cleaned with filtered air and packed inside an ISO Class 6 cleanroom environment using a specialized fluorine-based grease on internal seals.
  • Clean-Wash Package Options: Uses non-grease/oil-free assembly techniques with alternative packaging structures.

Standard Model Reference Codes

  • Straight Connectors: PC (Male Straight), POC (Inner Hexagonal Straight), PCF (Female Straight).
  • Elbow Configurations: PL (Standard Elbow), PLL (Extended Long Elbow), PLH (45° Elbow).
  • Tee & Branch Configurations: PB (Tee), PD (Branch Tee), PX (Branch Y).
  • Centralized Piping Modules: Triple types (PKD, PKG, PKJ) and twin triple variations (PKVD, PKVG) for high-density manifolds.

Material

Resin Body: Polybutylene terephthalate (PBT), used for the rotatable housing on shaped models like elbows and tees.

Metallic Body & Guide Ring: Nickel-plated brass, used for the structural base/threads on all models, and as the entire rigid body for straight connectors.

Release Ring: Polyacetal (POM), the plastic collar pressed down to unlock the tube.

Lock Claws: Stainless steel, the internal gripping teeth that hold the tubing securely in place.

Elastic Sleeve & O-Ring: Nitrile butadiene rubber (NBR), the primary internal sealing material.

Thread Sealant Coating: Sealock-coating, pre-applied to the tapered pipe threads.

Metric Thread Gasket: Stainless steel (SUS304) + NBR laminate composite
