Surface finishes that are too high or too low can reduce seal life.

U cup seal design guide.

Mfp offers a wide range of metric u cup designs and produces them from a broad range of materials. In addition to providing superior sealing in vacuum low and high pressure applications the polypak seal offers a number of distinct advantages over conventional symmetrical or non symmetrical u cup seals including. Head seals are a more reliable alternative to the standard o ring backup ring combination they resist twisting. Many different ucup configurations exist to properly seal that demanding application.

U cup seals or u ring seals are commonly used in linear applications to seal the rod or piston. Leak free seal from hard vacuum to over 60 000 psi with proper design and auxiliary devices. The u shape energizes the sealing lips as the application pressure increases. Symmetrical metric u cup seal u cup seal 4mm id x 10mm od x 4 5mm ht high temp urethane seal excellent wear and abrasion resistance up to 5000 psi applications symetrical lip design they can be used in rod or piston applications price is.
