Ank Seals

Rod Seals

The primary function of a rod seal is to prevent leakage from within the cylinder to the atmosphere . Leakage through the rod seal will not only reduce system performance , but also can contaminate the environment . Rod seals have to be carefully designed taking into consideration all the factors that influence their performance like temperature , pressure , gap extrusion , resistance to process media , low friction etc .

S10-12

S10-12 are Vee packs a.k.a Chevron packings . They are multiple-lip seals , usually composed of a male and female adaptor and a group of three or five vee rings .They are popular for sealing rods and pistons in medium to heavy duty applications and are compatible with both single and double acting cylinders .
MOC: Polyurethane + Acetal , Viton + PTFE .

S16

S16 is a single acting seal a.k.a hat seal . These seals are old generation seals .
MOC: Polyurethane , NBR , Viton .

Snow

S17

It is a single acting U cup seal with an additional back lip designed for light to medium duty applications .
MOC: Polyurethane , NBR , Viton .

Snow

S19

S19 is a single acting in which the Seal lips are initially energized with the help of a SS spring fitted into the u cup groove . This seal has a wide operating temperature range and wide chemical resistance . These seals are ideal for use in cryogenic applications .
