HRU 666 Block Vee U-cups

Homogenous U-cups (block vees) are a non-loaded, single material U-cup. The HRU seal is popular in low pressure applications where a low friction seal would be beneficial. The seal is most commonly used in pneumatic applications as a rod or piston seal. The design is suited for situations where space is limited or as an O-Ring replacement. The HRU seal is typically made from an 80 durometer Nitrile but also comes in FKM fluorocarbon, Neoprene and other homogenous materials.

As pressure is applied to the homogenous U-cup the seal experiences an increase in sealing force until it reaches the maximum pressure the seal can handle. Homogeneous U-cup seals can handle up to 500 PSI

O-Rings and Seals are very important to us and as part of our effort to "Make getting o-rings easy!", we have improved several areas of our business for 2020 and beyond. We needed more space for our expanding inventory so we added and additional 5,000 square foot warehouse space. We added several key people, Gary in our sales department, Savanna and Macey to our warehouse crew, Julian in our kit department and Steven to assist in the O-Ring Vulcanizing department. ISO Certification is underway and Melissa should have it completed early in 2020. Shipping department is reducing costs and increasing service by adding a defualt 2-Day Air Shipping Service for as low as $6.99. We make getting o-rings easy!

As a family-owned business we enter our 13th year of business in 2020 with great excitement. We have added additional inventory, product offering and great new staff members that not only make it easier to get o-rings, but for us it makes it great to come to work. Our plan is to continue adding new product and services to enhance our current offerings. Adding The O-Ring Store LLC as your O-Ring and seal supplier will improve your ability to repair or build your products and service. We know how hard it is just to get the product you need, by having a shop account and registering you will receive the appropriate business discounts, permanent cart, address book, and order history.

A sincere "Thank You" from my family and my work family, Marty C Frostad, GM and Owner.
