410 Series European Style Pneumatic Quick Connect Couplings

High-Flow, Safety-Enhanced, and Interchangeable Solutions for Demanding Applications

Product Overview

The 410 Series pneumatic quick connect couplings are engineered for high-flow performance and operational safety in compressed air systems. Compliant with European standards (EURO 10.5), these couplings feature a 10.4 mm bore diameter and support flows up to 3900 L/min at 6 bar. Their ergonomic design enables one-handed operation, making them ideal for automotive, industrial machinery, and heavy-duty pneumatic tools.

Series 410 is a safety coupling based on CEJN Series 410, a CEJN original and European standard. The Series is one-hand operated and offers long service life. It is a one hand operated safety coupling that vents before disconnection eliminating the risk of hose whip. The fully automatic operation ensures quick and easy handling. It complies with ISO Standard 4414 and has a steel front part as standard.

Key Features

1. High Flow Efficiency:

• 10.4 mm bore diameter minimizes pressure drop and maximizes airflow.

• Flow rates up to 3900 L/min ensure rapid tool operation and reduced cycle times.

2. Safety Mechanisms:

• Two-stage disconnection prevents accidental releases and complies with ISO 4414 and EN 983 standards.

• Pressure rating: 16 bar (230 PSI) for standard models, with some variants supporting up to 35 bar (507 PSI).

3. Durable Construction:

• Galvanized steel or brass body with NBR seals for corrosion resistance and longevity.

• Operating temperature range: -20°C to +100°C (NBR seals).

4. Interchangeability:

• Compatible with major brands including Rectus 27, Legris 27, Parker RF-3/8, Tema 1700, and CEJN 410.

• Available in BSPP (G), BSPT (R), NPT, and hose barb configurations.

5. Ergonomic Design:

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

Applications

• Pneumatic Tools: Grinders, impact wrenches, and drills requiring high airflow.

• Automotive Manufacturing: Assembly lines and tire servicing equipment.

• Industrial Machinery: Compressed air lines and automation systems.

• Heavy-Duty Equipment: Construction and mining applications.
