Product Description

Prevent grease backflow and maintain optimal system pressure with our High-Pressure Non-Return Valve Quick Connectors. Specifically engineered for centralized lubrication networks, these push-in check valves allow fluid to flow in only one direction, eliminating line drainage and air pockets when the pump is idle. Rated for extreme operating pressures up to 150 bar (2,175 PSI), they provide an instant, tool-free push-in connection for high-pressure polyamide (nylon) tubing, ensuring your machinery receives immediate, precision lubrication on every pump cycle.

Key Product Benefits & Features (Bullet Points)

Zero-Backflow Integrity: Features a highly responsive internal spring-loaded mechanism that instantly seals to prevent grease or oil from back-flowing.
Maintains Line Pressure: Keeps distribution lines fully primed between lubrication intervals, reducing wear and ensuring instant grease delivery.
150 Bar Pressure Rating: Built to withstand intense system pressures without leaking, making it ideal for progressive and single-line auto-lube setups.
Instant Push-In Locking: Heavy-duty internal stainless steel teeth securely grip high-pressure tubing for quick, tool-free installation.
Rugged Industrial Build: Machined from durable nickel-plated brass to resist corrosion, mechanical wear, and chemical breakdown in harsh operating environments.
