Its 50-state compliant, no-flame formula is ideal for safely loosening frozen bolts, fittings, and corrosion in industrial, automotive, and marine applications. ## Description You know the moment: the bolt won't budge, the line's down, and every minute costs more than you want to admit. You don't need promises- you need movement. CRC Knock'er Loose Plus uses freeze-shock technology to rapidly lower the temperature of the metal, causing it to contract. This cracks the rust and creates space for the industrial strength solvent to rapidly break the bond. For use om no-flame zones, it's the go-to when heat isn't an option. ## Features - CRC INDUSTRIES: A market leader that offers impeccably designed chemical solutions to maintain, protect and repair different marine, heavy-duty motor vehicles, industrial-grade engines, household tools and electrical equipment. - PENETRATING SOLVENT: Best for freezing fasteners in fuel/brake lines or no-flame zones. - UNIQUE FORMULA: Knock’er Loose offers a 50-state compliant formula that provides great performance in easing the disassembly of tools, automobile engines, plant machinery, and other equipment for routine maintenance. - APPLICATIONS: Knock’er Loose works effectively to dissolve and loosen rust and corrosion from couplings, bolts, fittings, locks, washers, sliding mechanisms, hinges, bushings, nuts, and other frozen components. - PRODUCT SPECIFICATIONS: This product is available in a 11.5 wt oz aerosol can. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0013IZS1O | | Best Sellers Rank | #39,945 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #223 in Industrial Lubricants #772 in Oils | | Brand Name | CRC | | Compatible Material | Metal | | Container Type | Can | | Customer Reviews | 4.6 4.6 out of 5 stars (524) | | Flash Point | 64 °C | | Global Trade Identification Number | 00078254030272 | | Included Components | Super Penetrant | | Item Form | Spray | | Item Type Name | Super Penetrant | | Item Weight | 13.28 ounces | | Liquid Volume | 11.5 fluid ounces | | Manufacturer | CRC Industries | | Material | Specialty compound | | Model Number | 03027 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 3027 | | Recommended Uses For Product | Electrical | | Specific Uses For Product | Prevent Corrosion | | UPC | 078254030272 | | Unit Count | 11.5 Ounce | ## Product Details - **Brand:** CRC - **Item Weight:** 13.28 ounces - **Liquid Volume:** 11.5 fluid ounces - **Material:** Specialty compound - **Package Information:** Can ## Images ![CRC Knock'er Loose Plus Penetrating Solvent - Rust and Corrosion - 11.5 oz - Image 1](https://m.media-amazon.com/images/I/51HRrmsV6DL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Frequently Bought Together - CRC Knock’er Loose Plus Penetrating Solvent 03027 – [Reddish] 11.5 WT.
