What Are SAP-SEAL® Products?

SAP-SEAL® screw-on is a patented plastic cap pre-filled (optional) with a rust inhibitor that is effortlessly applied to nuts and bolts to protect them from corrosion. SAP-SEAL® caps are made of polyethylene high-density plastic enabling the caps to withstand temperature fluctuations from -40°F up to 200°F.

SAP-SEAL® caps provide the best line of defense against corrosion where you use a nut and bolt – underwater (fresh and salt), above ground and underground.

SAP-SEAL® caps stay in place for many years. This longevity is very cost effective and while protecting against rust and corrosion, it also protects against accidental thread damage when performing maintenance.

SAP-SEAL® caps allow the end users to re-evaluate the purchasing of coated nuts and bolts.

SAP SEAL® caps are available in metric and U.S. units (inches) for bolt sizes ¼” to 3 ¾”. Custom colors and non-standard sizes as well as alterations to existing models are also available upon request.
