HYJET IV AND IVA Resistant O-Rings and Seals
HYJET IV and IVA is a polyalkylene glycol-based hydraulic fluid that is used primarily in aircraft systems and other hydraulically powered machinery. It is also used as a lubricant, antifreeze, and coolant. Common industries that use HYJET IV and IVA include aerospace, marine, and industrial manufacturing.
When rubber is exposed to HYJET IV and IVA, common failures can include swelling, cracking, and crumbling. Swelling is caused by the fluid's ability to permeate the rubber, making it become enlarged. Cracking can occur due to the fluid's high viscosity, which causes the rubber to become brittle and crack. Lastly, crumbling can occur due to the rubber's poor resistance to the fluid's physical and chemical properties.
EPDM (EP, EPR, Ethylene-Propylene Rubber)
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals. Marco Rubber has the world’s largest inventory network of EPDM o-rings and made on demand custom manufacturing often without tooling fees, so the EPDM o-rings you need are always available. Whether it’s for water systems, braking systems, medical, pharmaceutical, food or dairy use, you can count on Marco Rubber to deliver your o-rings fast and efficiently.
