Premium Pre-Energized Long-Life Vee-Packing

S1012


Premium Pre-Energized Long-Life Vee-Packing

Premium Vee-packing that does not require the tightening of the gland to maintain a positive seal due to the pre-energized design and material of the Vee-rings, leading to 3 to 4 times the service life over traditional rubber fabric Vee-packing. Retro fits seals of similar design.

*Important Note: Maximum values above depend on extrusion gap, clearances, seal material, media, temperatures, pressures, surface speed, dynamic running surface finish and working environment. Seals cannot be operated at their upper ratings at the same time. Pressure ratings can be increased by reducing clearances. For pressure above specified operating pressure, please contact engineering@ahpseals.com
