O-Rings and O-Ring Kits
O-rings are doughnut-shaped gaskets used in static or dynamic applications for sealing machinery. They are manufactured by techniques like extrusion, compression, injection and transfer moulding. Raptor Supplies offers a wide range of these O-rings & backup rings, along with O-ring accessories, kits & splicing kits from brands like Texas Pneumatic Tools, Banjo, Little Giant Pumps, Detecto and Vulcan Hart. These O-rings are offered in nitrile rubber, silicone, polyurethane, neoprene and fluorocarbon material variants in black, blue, brown, red & white colours. The back-up rings or anti-extrusion rings are thin rings designed to prevent O-ring extrusion, under pressure, by providing added resistance. They come in the form of a solid ring, a split ring or even a spiral ring, depending on the requirements of the sealing system.
