Technical Overview

Straight push-pull pneumatic fitting with male R3/8 thread and 6mm push-in port. Features nickel-plated brass housing, PTFE seal, and -0.95 to 8 bar pressure.

Key Features

  • Push-pull connection principle for simple, tool-free tubing installation and removal
  • Male R3/8 tapered thread with pre-applied PTFE thread sealant coating
  • Designed for standard 6 mm outside diameter pneumatic tubing
  • Durable nickel-plated brass housing with POM release ring and NBR seal
  • Wide operating pressure range of -0.095 MPa to 0.8 MPa (-0.95 bar to 8 bar)
  • Class 4 cleanroom suitability according to ISO 14644-1
  • RoHS-compliant and free of copper, zinc, or nickel on primary external contact zones (VDMA24364 zone III LABS conformity)

Constructed with a robust nickel-plated brass housing and a stainless steel tube-retaining claw, featuring a pre-applied PTFE thread coating for instant, secure sealing without additional sealant tapes.

Industrial Applications

1. Pneumatic Control Panels in Cleanroom Packaging Lines

Using its certified ISO Class 4 cleanroom suitability and VDMA24364 zone III (LABS/PWIS conformity), this fitting is deployed in medical device or electronic components packaging lines. It facilitates the distribution of dry compressed air through 6 mm tubing, ensuring zero paint-wetting impairment.

Problem Solved

Prevents contamination of products and packaging equipment from outgassing or particle emissions, which would otherwise ruin sensitive components or paint-adhesiveness on packaging.

2. End-of-Arm Tooling (EOAT) in Pick-and-Place Systems

The lightweight straight design (23.17g) and standard 6 mm OD connection allow direct integration onto robot arms or pick-and-place end effectors operating within -0.95 to 8 bar vacuum/pressure. The push-pull principle allows rapid replacement of tubing during preventative maintenance.

Problem Solved

Reduces payload drag and avoids bulky setups on robotic joints while providing a secure lock via the stainless steel retaining claw to withstand high acceleration forces.

3. Industrial Manifold Compressed Air Distribution

Screwed into manifolds with R3/8 female threads, this fitting routes main supply lines down to individual 6mm pneumatic actuators. The pre-coated PTFE sealant on the tapered R3/8 thread enables fast, leak-free assembly directly onto manifolds without using liquid sealants or Teflon tape.

Problem Solved

Eliminates the risk of excess tape or paste debris entering and damaging downstream pneumatic valves or cylinders during manifold assembly.
