Flaretite’s new bonnet seal fits all standard ¼-inch flared SAE fill connections. These seals make any fill connection fitting permanently leak-free, and still allow serviceability should the connection require servicing. Flaretite bonnet seals are copper stampings coated with a dry-to-the-touch Loctite sealant, utilizing the company’s sealing ring technology. Simply place the bonnet seal onto the nose of the fill connection, prior to installing the cap. The fitting should then be tightened to its recommended torque.
