JB-80 is Justice Brothers’ flagship multi‑use lubricant and penetrating oil, designed to handle everything from stuck bolts on rusty chassis components to squeaky shop doors and equipment. Its low‑viscosity formula penetrates into tight clearances, cutting through rust, corrosion, grease, and grime so you can free heavily rusted parts without excessive heat or impact. Once applied, JB-80 leaves a thin lubricating film that reduces friction on metal‑to‑metal contact surfaces and helps extend component life in harsh environments.
For diesel and automotive applications, JB-80 is commonly used on exhaust fasteners, suspension hardware, door and hood hinges, latches, linkage, and general shop tools where rust and seized components are routine. It’s also suitable for light industrial, agricultural, and household use on locks, chains, gates, and any mechanism where squeaks and binding are a problem. The formula displaces moisture, making it useful after pressure washing or wet weather to help protect exposed metal and assist in drying ignition system components or electrical connectors.
This listing is for a 6‑pack of 13 oz aerosol cans, giving you enough inventory to stock multiple bays, service trucks, or tool cribs while maintaining consistent lubricant performance across all jobs. Each can is labeled JB/80 or JB80, and the product is supplied by Justice Brothers as a new, packaged aerosol penetrant.
There are common symptoms that indicate a need for a quality penetrant and lubricant like JB-80 in diesel and automotive environments:
Fasteners that are seized or extremely difficult to remove due to rust or corrosion (broken studs risk).
Squeaks and creaks from door hinges, hood hinges, suspension bushings, or steering linkages.
Binding or stiff operation of latches, locks, throttle or shift linkages, and cable mechanisms.
Visible rust on hardware, brackets, clamps, or tools that are regularly exposed to moisture.
Water intrusion after washing or driving in rain leading to misfires or intermittent electrical issues where moisture displacement can assist.
Justice Brothers generally offers JB-80 as a consumer/industrial chemical product without an extended mechanical warranty; performance is based on proper use as a penetrant and lubricant on compatible materials. NorCal Diesel Performance supports these shop supply products under our standard returns policy, which may include return eligibility for unopened, unused cans within a defined time window.

Q: What’s the primary difference between JB-80 and a generic penetrant?
A: JB-80 is positioned as “TWICE AS GOOD” and combines a deep‑penetrating rust‑busting action with JB Metal Conditioner and a corrosion‑inhibiting film, giving both short‑term freeing power and longer‑term protection compared to many basic penetrants.
Q: Can JB-80 be used on electrical components?
A: JB-80 displaces moisture and can be used to help dry and protect metal parts around electrical connections, but it should be applied sparingly and with care, avoiding sensitive plastic or rubber materials that are not rated for petroleum‑based products.
Q: Is JB-80 safe on painted surfaces and plastics?
A: JB-80 is formulated primarily for metal surfaces; avoid over‑spray on painted, plastic, or rubber components that may be softened or stained by petroleum‑based solvents, and always test a small area first if in doubt.
Q: How should the cans be stored?
A: Store JB-80 aerosol cans upright in a cool, dry, well‑ventilated area away from open flames, sparks, and high heat, following standard aerosol and lubricant storage guidelines and any safety recommendations on the product label.
Q: Is JB-80 suitable for heavy diesel shop use?
A: Yes, JB-80 is widely used in automotive and heavy equipment environments to free rusted hardware, protect tools, and keep hinges and linkages operating smoothly, making this 6‑pack configuration well‑suited for diesel repair facilities.
