Our new 558 LC Series Insert Chek™️ Valve offers more than a 67% increase in flow capacity over the existing 558 series check valve. Designed for reliable operation, the new valve features robust, stainless steel construction, providing compatibility with a wide range of fluids and gases. A high-quality metal to metal seat provides low leakage and highly repeatable cracking pressures. This robust design and 100% functional testing ensures consistent long-term performance.
Simple to install, the new check valve uses Lee’s field-proven insert principle that provides secure retention and eliminates the need for threads, o-rings or in- house designs. To install, simply insert the check valve into a drilled installation hole and drive the expansion pin flush to seal and lock the valve in place.
The new 558 LC Chek Valve’s compact size, superior performance, and ease of installation make it ideal for high volume applications in automotive, off-road, and other industrial hydraulic systems.
