Description
The JGDI is a rod combination seal that is resistant to multiple fluids.
It consists of four parts: a slide ring made of filled PTFE material, two L rings with POM material and a energiser O-ring. The L ring acts as a support and guide to ensure a tight seal. The sealing ring relies on the force of the O-ring to press the piston rod, providing a reliable sealing.
