Forespar MareLube TEF45 High-Load PTFE Grease — 4 oz Jar, MPN 770067 and Mariners Warehouse SKU 73218, supplies the exact 4 oz jar for high-load lubrication, anti-seize and dissimilar-metal corrosion barrier. Choose it by the component material, lubricant specification and permitted service method. Collection placement does not establish compatibility with every RV valve, seal or repair surface.

TEF45 uses 45% PTFE micropowder in synthetic grease for supported high-load, anti-seize and corrosion-barrier applications. Manufacturer examples include threaded hardware, turnbuckles, rigging fittings and specified metal service areas. It is a lubricant/barrier rather than a threadlocker, structural adhesive or replacement for a damaged component. Match any lubricated fastener’s assembly and torque procedure to the equipment instructions. The 4 oz jar format suits transfer with an appropriate separate applicator and the planned service quantity.

Make the assembly safe to service, remove contamination as directed and apply only at the manufacturer-approved contact surfaces. Use the component’s lubricant specification, quantity and assembly procedure rather than an invented universal grease dose. For any electrical application, follow the equipment’s safe isolation and connection instructions; dielectric grease is not a conductive repair compound. Keep product off surfaces requiring a dry or friction-controlled interface, close the container or syringe after use and follow the current label/SDS for handling, storage and disposal.

Application Guides

Match the Repair Material to the Substrate and System

Check 770067 by its actual edge-trim or lubricant role. Confirm substrate/component, profile or formula, preparation, application method and package contents before choosing.

TEF45 4-Ounce or 16-Ounce Jar?

770067 supplies the 4-ounce TEF45 grease jar; 770068 supplies the separate 16-ounce jar. The formulation role remains high-load lubrication, anti-seize and a corrosion barrier on documented compatible surfaces. Quantity changes without adding a component-service kit.

Choose the jar size for the planned work and a suitable separate applicator. Do not treat the larger jar as stronger grease or a substitute for the component’s lubrication and torque requirements. Syringe packs are separately sold formats when their access method suits the task. Review the Forespar MareLube TEF45 High-Load PTFE Grease — 16 oz Jar as a separately sold option.
