Smc Pneumatics ASP530F-03-08S Check Valve 3/8x1/8

Product Description

The SMC PNEUMATICS ASP530F-03-08S is a push-to-connect check valve designed for use in compressed air and pneumatic fluid control systems. It features a nickel plated brass body, a nitrile butadiene rubber (NBR) seal, and a stainless steel spring for reliable one-directional flow control. The valve accepts an 8 mm tube outside diameter on the push-to-connect end and connects to a 3/8 x 1/8 inch pipe fitting. Operating temperature range spans 23 degrees F to 140 degrees F. This part is typically installed by industrial maintenance technicians, mechanical contractors, and pneumatic system specialists.

The ASP530F-03-08S is suited for light industrial and automation applications where controlled directional airflow is required. It is commonly used in pneumatic circuits to prevent backflow, protect sensitive components, and maintain system pressure when a line is disconnected. The push-to-connect configuration allows for tool-free tube insertion, making it practical for panel builds, manifold assemblies, and inline pneumatic plumbing in both production and maintenance environments.

Key Features

• Push-to-connect end connection for tool-free 8 mm tube installation
• Nickel plated brass body for corrosion resistance in industrial environments
• NBR seal material compatible with standard compressed air service
• Stainless steel spring for consistent check performance and long service life
• Operating range of 23 degrees F to 140 degrees F suits most indoor pneumatic applications
• 3/8 x 1/8 inch pipe size for straightforward inline integration

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic systems utilizing 8 mm outside diameter tubing with 3/8 x 1/8 inch pipe connections in compressed air circuits.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system service. Depressurize the system and vent all residual air pressure before removing or installing any valve component. Verify tube outside diameter and pipe thread size match before installation, and inspect the push-to-connect collet and seal for damage prior to assembly. Follow applicable local codes and the equipment manufacturer guidelines for pneumatic component replacement.
