When part numbers are missing, seal dimensions are unknown, and the parts themselves are unavailable from the equipment OEM, these o-ring kits can save the day, not to mention hours of downtime. These kits come in a choice of compounds and o-ring sizes (standard, metric and tube) for a wide range of sealing applications. The end result? Multiple sealing solutions for the same cost as a single OEM replacement part. Austin Seal will even build custom kits using any combination of o-ring sizes out of Buna and Viton.
