Max.: 500 bar (7,252 psi)
Merkel compact seal T 42 for sealing pistons features back up rings. The seal allows dual-side pressurizing in pushers, plungers, and subsidiary cylinders used in self-advancing support systems. The seals provide excellent extrusion protection, including at peak pressure.
T 42 provides high abrasion resistance. The profile ring made of rubber provides high contact pressure.
