Series 320 Pneumatic safety close type quick couplings

Series 320 Pneumatic safety close type quick couplings

Product Overview

The 320 Series pneumatic quick connect couplings are engineered to deliver exceptional flow efficiency and durability for compressed air systems. Designed to European standards (EURO 7.6), these couplings feature a large 7.6mm bore diameter and support flows up to 2100 L/min at 6 bar14. Their ergonomic design allows for one-handed operation, making them ideal for high-demand environments like automotive manufacturing, industrial machinery, and pneumatic tools.

Key Features

1. High Flow Performance:

• 7.6mm bore diameter minimizes pressure drop and maximizes airflow efficiency14.

• 2100 L/min flow capacity ensures rapid tool operation and reduced cycle times4.

2. Robust Construction:

• Galvanized steel body with NBR seals and hardened zinc-plated sleeves for corrosion resistance and long service life14.

• Operating temperature range: -20°C to +100°C13.

3. Safety and Compliance:

• Two-stage safety mechanism prevents accidental disconnection and complies with ISO 4414 and EN 983 standards1.

• Pressure rating: 16 bar (230 PSI) with a minimum burst pressure of 140 bar (2030 PSI)14.

4. Interchangeability:

• Compatible with major brands including Rectus 25/26, Legris 25/26, Tema 1600, and Bosch Size 326.

• Available in BSPP (G), BSPT (R), NPT, and hose barb configurations (e.g., 8mm, 10mm, 1/4", 3/8", 1/2")14.

5. Ergonomic Design:

• Single-handed coupling/decoupling reduces operator fatigue and improves productivity5.
