You will find this material specified across fluid power, construction equipment, and agricultural equipment.

H7X387 ships individually. Unit weight is approximately 58.95 g. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
