Dexter Diaphragm Filler Cap 068-147-00 for Model 60 Aero 7500 Trailer Brake Actuator

The Dexter diaphragm filler cap, part number 068-147-00, is the reservoir cap used on Model 60 Aero 7500 trailer brake actuators. It seals the top of the hydraulic actuator's fluid reservoir while the internal diaphragm flexes to accommodate normal changes in brake fluid level as the actuator cycles, helping keep the reservoir sealed against contamination and moisture. This is a small, lightweight component at just 0.04 pounds, sized to fit the compact reservoir opening on the Model 60 Aero 7500 actuator housing. Because the filler cap and its diaphragm are wear items exposed to fluid, heat, and repeated actuation cycles, they can crack, harden, or lose their seal over time, which allows moisture and debris into the reservoir or lets fluid weep past the cap. Replacing a worn or damaged cap with the correct part restores a proper seal on the reservoir without needing to replace the entire actuator. This cap is intended specifically for use on Model 60 Aero 7500 trailer brake actuators.

Frequently Asked Questions

What is the Dexter 068-147-00 filler cap used for? It is the diaphragm filler cap that seals the fluid reservoir on a Model 60 Aero 7500 trailer brake actuator, allowing the diaphragm to flex with normal fluid level changes while keeping contamination out.

Does this cap fit Titan Model 60 trailer brake actuators? Yes, part number 068-147-00 is designed to fit Model 60 Aero 7500 trailer brake actuators.

What size is the replacement filler cap? The 068-147-00 cap measures 1.5 x 1.5 x 1 inches, a compact size matched to the Model 60 Aero 7500 reservoir opening.

How much does the filler cap weigh? The Dexter 068-147-00 diaphragm filler cap weighs 0.04 pounds.

Is this a genuine Dexter part or an aftermarket copy? Part number 068-147-00 is the Dexter part number for this diaphragm filler cap, not a generic aftermarket substitute.

What does the diaphragm inside the cap actually do? The diaphragm in the 068-147-00 filler cap flexes to accommodate normal fluid level changes in the Model 60 Aero 7500 actuator's reservoir while keeping the reservoir sealed.

How do I know if my actuator's filler cap needs replacing? A cracked, hardened, or leaking diaphragm cap on a Model 60 Aero 7500 actuator will let fluid weep past the seal or allow moisture into the reservoir, both signs that the 068-147-00 cap should be replaced.

Can this cap be used on other actuator models besides the Model 60 Aero 7500? Part number 068-147-00 is specified for the Model 60 Aero 7500 trailer brake actuator.

Does the 068-147-00 cap seal the reservoir opening completely? Yes, the diaphragm filler cap seals the top of the Model 60 Aero 7500 reservoir while its internal diaphragm allows for fluid expansion and contraction.

Why would a trailer brake actuator need a new filler cap instead of a full actuator replacement? If only the diaphragm filler cap on a Model 60 Aero 7500 actuator has failed, replacing the 068-147-00 cap restores the reservoir seal without replacing the entire actuator assembly.
