Kalrez O Ring Shelf Life
This product was specifically developed for the chemical and hydrocarbon industries to provide improved chemical and thermal resistance better than the industry standard set by kalrez 4079.
Kalrez o ring shelf life. Actual lead times will be established at the time of the order placement. Previously known as arp5316 recommended practice this standard is based upon both cumulative studies and industry input regarding practical storage limits and fifo requirements. Arp 5316 is often used as a guideline in determining useful shelf life of elastomers used in other industries. Kalrez 6375 compounds are widely used in the chemical process industry as they have excellent broad chemical resistance and mechanical properties.
Dupont kalrez 4079 is a low compression set product for general purpose use in o rings. Dupont and its local authorized distributors of kalrez parts maintain inventories of many standard as 568 o rings. Kalrez spectrum 7075 o rings have a glossy finish. Kalrez 7075 can perform in high temperature o ring environments up to 620 ºf 325ºc.
Kalrez spectrum 7075 offers the enhanced elastomeric properties outlined above while providing a chemical resistance better than the industry standard set by kalrez 4079. Kalrez 4079 compounds feature low compression set performance o rings. It was issued in 1998 to supersede mil hdbk 695 as the aerospace industry standard in governing o rings and molded seals shelf life. O ring shelf life compliance standard.
