subject: Piston Seals Offer Finest Sealing Requirements [print this page] Most industries operating in the milieu of mechanical, automotive, pharmaceutical, manufacturing etc require fool-proof sealing systems. Piston seals are among the most preferred sealing methods because the lack of proper sealing might lead to some dangerous situations. Different companies look out for different sealing applications and the market today offers a wide variety of specially designed seals in different shapes, sizes and materials. Since such seals come in constant and close contact with various kinds of materials, chemicals and pressure levels, it is important that they are safe, durable and sturdythe quality of seals should take precedence over all other factors including cost.
To elaborate a little on the exact function that such a seal carries out these seals are designed in such a manner that fluids or gases under pressure do not spill or leak between the piston and the bore. Since they perform such a critical task, it is important that you check if the best quality raw materials have been used while manufacturing these seals. The production techniques and engineering standards applied while producing these seals also play an equally crucial role.
Parker-o-rings are among the finest types of such seals available in the market today and their dependability in industries makes them increasingly popular. O-rings are basically called so because they are round in shape and are manufactured from elastomeric compounds made from either natural or synthetic rubber. These rings are becoming the preferred choice of industries because they are engineered with precision and deliver the highest quality. What adds to their ease of use is the fact that they come in varied sizes and hardnessthis helps in choosing the best product according to your need. These rings are available in standard as well as metric sizes. While choosing these rings, make sure to do a background check on the compatibility of these rings with different kinds of chemicals. You must carefully consider and consult the pros and cons of the ring that you choose and the kind of chemical that comes in contact with. These rings should be able to withstand high temperatures too.
Another variety, known as Teflon Backup Rings are increasingly useful in dealing with high-pressure systems and production lines. These rings, used in conjunction with Parker-O-Rings provide ideal solutions in the most demanding and critical situations. This combination works in high pressure and high temperature conditions as well. Teflon Backup Rings are available in single turn, multi turn and static configurations.
When choosing your piston seals, always remember that these small yet critical parts have to last you for several years to come and hence must be of top-notch quality. Choosing the best quality also ensures that you will have to spend less time and money in undertaking maintenance work.
