Series 210 Interchange Quick Connect Air Couplings air safety couplings
Product Overview
The 210 Series Standard Pneumatic Quick Connect Couplings are engineered for high-flow performance and reliable operation in compressed air systems. These couplings are designed to be interchangeable with major industry standards (e.g., ARO 210 series) and are widely used in industrial applications due to their robust construction and ease of use. With a typical 1/4-inch size and support for pressures up to 300 psi (20.6 bar), they are ideal for pneumatic tools, automation systems, and compressed air lines.
Key Features
High Flow Efficiency:
Large bore design minimizes pressure drop and maximizes airflow, ensuring efficient tool operation.
Flow-optimized valve mechanism reduces cycle times and improves productivity.
Interchangeability:
Compatible with ARO 210 series, Parker 50/HA series, and other industry-standard couplings.
Available in multiple connection types (BSPP, BSPT, NPT, hose barb) for seamless integration.
Durable Construction:
Materials: Bodies are typically made from brass or carbon steel with zinc plating for corrosion resistance. Seals are NBR (Nitrile Rubber) or FKM (Fluorocarbon Rubber) for wide temperature range compatibility (-20°C to +100°C with NBR, up to +180°C with FKM).
Pressure Rating: Standard models handle up to 300 psi (20.6 bar), with some variants supporting higher pressures.
Safety and Reliability:
Single shut-off valve design prevents air leakage during disconnection.
Push-to-connect sleeve allows for one-handed operation, enhancing operator convenience and safety.
Ergonomic Design:
Series 210 couplings offer high flow and require only a low connection force, which ensures a safe working environment. It is a one hand operated safety coupling that vents before disconnection eliminating the risk of hose whip. Male threads on the couplings and nipples feature pre-applied thread sealant. A fully automatic operation ensures quick and easy handling. It complies with ISO Standard 4414.
Series 210 is also available in Soft-Line and Multi-Link versions.
