1/2-Inch Inline Check Valve for Compressed Air Systems

Brief Overview

This 1/2-inch inline check valve is a straightforward, no-nonsense solution for directional air flow control in compressed air systems. Built from nickel-plated brass with an NBR seal, it handles the essential task of preventing backflow in pneumatic circuits across production, medical, construction, automotive, and industrial applications. If your customer base needs reliable flow control without complexity, this valve pairs well with complementary smaller 3/8-inch check valves and 1/4-inch alternatives for varied system configurations.

Key Features

• Compact inline design with hexagonal end fittings for tool-free installation (wrench-compatible)
• Nickel-plated brass body delivers corrosion resistance and durability in industrial environments
• High abrasion and impact resistance ensures reliable performance under sustained pressure cycles
• NBR seal provides consistent one-way flow control without maintenance
• Wide fluid compatibility: Compressed air, water, oil, and non-corrosive fluids
• Extended temperature range: -5°C to +60°C operational window covers most shop environments
• High flow capacity: 2500 L/min supports multi-tool systems without pressure loss

Business Advantages for Resellers

• High-margin consumable-adjacent product: Check valves are installed components with long service life—customers order them once but return for system upgrades or replacements
• Entry-level pressure systems: The 10 bar rating positions this valve perfectly for light-to-medium industrial applications, creating natural upsell opportunities to higher-pressure systems
• Bundle potential: Stock this alongside larger and smaller sizes to offer complete system solutions to workshop chains and maintenance departments
• Minimal warranty exposure: Solid brass construction and proven sealing design reduce returns and support costs
• Stock stability: One-way valves don't trend—they're permanent inventory that moves steadily across sectors
