O-Ring Cord

We stock O-Ring cord in all popular metric and imperial sizes

In this area of our website, you will find information on our range of O-ring cords. The O-ring cord that we supply is an endless length of extruded cord and is suitable for applications where standard O-ring sizes are not available, such as when you need a particularly large or custom size. O-ring cords allow you to create your own o-rings to whatever size your application demands. It can be used in conjunction with Loctite 406 instant adhesive for rubber. Please note that if you are ordering more than one (of the same size), the cord will come as one whole length.

Hydraulic Cylinder Seals

Hydraulic Cylinder Seals: Performance and Durability

Hydraulic systems are sealed using a combination of specialized seals. Hydraulic Rod seals prevent leakage of fluid from within the cylinder to the outside while hydraulic piston seals prevent fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the Cylinder extend or retract. Wear rings guide the piston and piston rod within the hydraulic cylinder, absorbing transverse forces, preventing metal-to-metal contact. Scrapers or Wipers scrape dirt, foreign particles, chips or moisture from the piston rods as they retract into the cylinder, preventing contamination.

Our focus isn’t just on the rapid, cost-effective delivery of new and replacement parts – it’s equally fixed on delivering long-term reliability solutions that exceed even the highest customer expectations. We don’t see ourselves as a supplier but as a business partner, working alongside customers to deliver added value throughout the supply chain and beyond. We offer inventory management, engineer call-out, training, water-saving audits and a competitor repair/ replacement program, as well as a range of reliability services through our customer collaboration site-service program. Our philosophy is simple: we’ll do whatever it takes to deliver, wherever and whenever it’s needed. Our aim is to consistently exceed expectation and meet even the most complex briefs and challenging lead times. Through continuous investment, unique modular technology and an unparalleled dedication to customer service we aim to constantly exceed expectation.
