Dear Valued Buyer, As a leading manufacturer in the industrial tools sector, Cangzhou Dean Safety&Special Tools Co., Ltd (established 2001, annual export value above US$100 million) proudly presents our Double-Ended C-Wrench 12 inch with 1 Year Lubrication Warranty and Mill Test Report Provided. This tool is engineered for professionals who demand reliability, durability, and precision in pipe fitting and mechanical maintenance. With over two decades of manufacturing expertise, we ensure every wrench meets rigorous quality standards before reaching your hands.
Product Overview: This double-ended C-wrench features a reversible jaw design that allows you to work on both standard and oversized nuts or pipes without changing tools. The 12-inch length provides excellent leverage while maintaining control. Each wrench comes with a 1-year lubrication warranty ensuring smooth operation, and a Mill Test Report (MTR) is provided to verify material composition and mechanical properties.

Key Features and Benefits:
- Double-Ended Design: One end features a standard C-jaw for general pipe work, the other end has an offset version for tight spaces. This eliminates the need for multiple wrenches.
- 1-Year Lubrication Warranty: Our patented lubrication system keeps the adjusting screw moving freely even under heavy use. If the mechanism seizes within one year, we replace the tool free of charge.
- Mill Test Report (MTR) Provided: Each batch of steel is tested for tensile strength, yield point, and chemical composition. You receive a detailed MTR to verify material quality – ideal for regulated industries.
- Ergonomic Handle: The 12-inch length provides optimal torque without excessive weight. The handle is contoured for a comfortable grip, reducing hand fatigue during prolonged use.
- Reversible Jaw Screw: The adjusting screw is designed for smooth reversal, allowing you to quickly switch between tightening and loosening without removing the wrench from the work piece.
- Rust-Resistant Coating: Black oxide finish offers corrosion resistance and reduces glare. Custom finishes (chrome, zinc plating) are available upon request.
- Versatile Applications: Suitable for pipe fitting, hydraulic systems, heavy machinery maintenance, and automotive repair. Works on both metric and imperial sized nuts/pipes.
Why Choose Our Double-Ended C-Wrench? Unlike ordinary pipe wrenches, our tool incorporates advanced forging techniques and strict quality control. Each unit is individually tested for jaw alignment and screw movement before packaging. The 1-year lubrication warranty gives you peace of mind, knowing your tool will perform consistently. With a typical service life exceeding 5 years under normal use, this wrench offers excellent return on investment.
Trust & Reliability: Backed by our company’s strong track record – over US$100 million annual export value, supplied to markets including North America, South America, Europe, Southeast Asia, and Africa. We ship from Tianjin, Shanghai, and Ningbo ports with professional packaging to prevent damage. Our factory has been in operation since 2001, meaning we understand the demands of global industrial clients. We are committed to providing tools that exceed expectations.
