The SNAP-CHECK quick-connect plug, manufactured in Sweden, is a high-performance solution designed for precise pressure measurement in hydraulic systems. Engineered from galvanized steel and sealed with durable NBR, it guarantees exceptional resistance and reliability even in demanding conditions, with an operating temperature range from -30°C to +100°C. The hardened steel plugs are permanently installed in the hydraulic circuit and feature integrated shut-off valves, ensuring safety and efficiency. When paired with quick-connect sockets and a pressure gauge via a hose, the system enables accurate measurements under pressure up to 300 bar. Both connected and unplugged plugs operate at a working pressure of 600 bar, with impressive burst resistance of up to 2400 bar for the unplugged plug and 1300 bar for the connected assembly. The precisely engineered construction ensures leak-free performance and long-lasting durability, while the standardized red protective caps provide additional safety and easy identification. Thanks to its versatile connection range, the SNAP-CHECK plug allows for flexible configuration of measurement points, making it an indispensable component for professionals seeking reliable, efficient, and safe hydraulic diagnostics.
