Universal Rod or Piston U-Cups

Universal Rod or Piston U-Cups

Universal Rod or Piston U-Cups or U-Rings are popular due to the small gland space required. They are usually specified in low speed, low pressure environments for both pneumatic and hydraulic cylinders. The symmetrical design seal is obtained by means of the flared, flexible lips coming in contact with the rod or cylinder wall. Clearance is provided at the heel for minimum friction. Seal effectiveness is increased as internal pressure increases against the inner surface of the lips. Many different U-Cup configurations exist to properly seal that demanding application. The O-Ring Store LLC offers a wide range of U-Cup designs and produces them from a broad range of materials. Loaded U-Cups, Non loaded U-Cups, Hydraulic or Pneumatic U-Cups We make getting U-Cups easy!

The O-Ring Store LLC, We make getting o-rings easy!!

The O-Ring Store LLC began in 2007 supplying O-Rings primarily to the large Paintball industry including our own shop and field. Over the last decade we have been fortunate enough to supply O-Rings and Hydraulic Seals to tens of thousands of customers in every industry. The crew is comprised of friends and family that work hard for each other and everyone that relies us to be their O-Ring supplier. Outside a select few, the big O-Ring brand service levels have became counterproductive to real customer service so we have been developing a network of partners with unique capabilities that allow us to provide a multitude of products, materials, and production capabilities to ensure our customers receive the best product and service options possible. This has allowed us our own line of branded materials which utilize the same raw polymers and contract manufacturers as the big brands, but without the overhead, complications and attitudes that result in high prices in lead times. Currently we stock over 50,000,000 O-Rings and Seals . Due to customer requests and to better our processes, we have begun the process to be ISO 9001 Certified in the first quarter 2020. It has been and will continue to be a wonderful journey with challenges and rewards. Thank you for your support and confidence.
