Technical Overview

The Festo 162867 (CRQS-3/8-12) is a premium straight-form high-alloy stainless steel push-in pneumatic fitting. Engineered for demanding industrial environments, it features a male R3/8 threaded connection and a 12mm push-in tube outlet. Manufactured with an FPM tubing seal, it provides maximum corrosion resistance (CRC 4) and handles operating pressures from -0.95 to 10 bar. The fitting is food-safe, FDA-compliant, and suited for high-temperature and chemical washdown applications, operating across temperatures from -15°C to 120°C.

Key Features

  • R3/8 (BSPT 3/8") male threaded connection to 12mm push-in tube connector
  • High-alloy stainless steel body and release ring with high-performance FPM tubing seal
  • Maximum corrosion resistance class (CRC 4) for extreme chemical and washdown environments
  • Operational pressure range covering -0.95 to 10 bar (-13.8 to 145 psi) and vacuum applications
  • Wide ambient temperature tolerance ranging from -15°C to 120°C
  • Food-safe, FDA-compliant design highly resistant to hydrolysis and aggressive cleaning agents
  • Integrated 21mm external hexagon for fast, secure, and optional position inline installation

Industrial Applications

1. Clean-in-Place (CIP) Food Packaging Actuation

In food and beverage processing lines, pneumatic connections must withstand rigorous high-temperature washdowns using caustic cleaning chemicals. The CRQS fitting ensures sterile and leak-free operation for pneumatic actuators guiding packaging robotic arms.

Problem Solved

Prevents rust, degradation, and contamination in sterile environments by leveraging CRC 4 high-alloy stainless steel and FDA-compliant materials.

2. Corrosive Media Handling in Chemical Mixing

Automated chemical manufacturing plants require robust pneumatic systems to control dosing valves in environments exposed to corrosive vapors and alkalis. This fitting provides a secure inline connection from pneumatic control lines to heavy-duty dosing cylinders.

Problem Solved

Avoids premature failure and pneumatic leaks common with standard brass or plastic fittings when exposed to aggressive industrial chemicals and hydrolysis.

3. Pneumatic Control in Industrial Autoclaves

Steam sterilization and industrial autoclave equipment operate at elevated ambient temperatures. The stainless steel push-in fitting securely routes pneumatic pressure to chamber-locking mechanisms without thermally degrading.

Problem Solved

Resolves the issue of pneumatic seal failure and plastic deformation at high temperatures, functioning reliably up to 120°C with its FPM tubing seal.
