Festo Sealing Ring

This piston seal kit from Festo ensures your pistons keep working efficiently. It forms a tight seal around the piston port to prevent leaks, maintaining your system's air pressure for effective pneumatic performance. As it's made from flexible PVC, the O-ring adjusts under compression to ensure a consistently uniform seal even at high speeds. It's designed for industry-standard G1/2 threaded pistons, so is widely compatible with commonly used equipment. Thanks to its 47.9Nm nominal tightening torque, this sealing ring achieves a strong hold on your hardware for a secure installation.

O-rings stop leaks from disrupting your system's air pressure. By improving the performance of your equipment, they dampen operating vibrations and support stable running.
