Featured Product from Lee Co. (The)
The 281 Zero Leak PRI® is a new pressure relief insert for thermal relief and low flow hydraulic pressure relief applications where zero leakage is needed. Weighing only 6 grams, typical flow rates range from a few mL's per minute for thermal relief applications, and up to 0.5 GPM for low flow pressure relief applications.
Working temperature is -65 °F to +275 °F and the cracking pressure is preset at the factory with capabilities ranging from 800 psid up to 4700 psid. Each Zero Leak PRI is 100% tested and inspected to ensure reliable, consistent performance.
