This guide is for mechanics, automotive technicians, and DIY enthusiasts working with vehicle cooling systems or fluid lines. The PetrolScooter 37178 Ear Type Water Pump Hose Line Clamp Pliers offer a precise and secure way to temporarily block fluid flow without damaging hoses, simplifying tasks like component replacement or maintenance. A potential caveat is the specific jaw opening size, which may not suit all hose diameters.

The maximum jaw opening is 22 mm (0.87 inches), which dictates the maximum outer diameter of the hose that can be effectively clamped.
These pliers are best suited for low to medium-pressure lines such as coolant hoses, vacuum lines, and some standard fuel lines. They are not designed for high-pressure hydraulic or fuel injection systems.
No, these pliers are specifically designed for flexible hoses and tubing. Using them on rigid materials may cause damage to the tool or the tubing.
The product description indicates they are made from durable, corrosion-resistant materials, suitable for workshop environments.
Wipe clean with a dry or slightly damp cloth after use and store in a dry location. Periodically check for and clean any debris from the jaws.
The overall length of the pliers is 240 mm (9.45 inches).
Ensure the hose is within the maximum jaw opening capacity (22 mm). Check jaws for any debris or damage that may be preventing a full grip. Ensure the handles are fully closed.
Loosen the clamp slightly. The hose material may be very soft. Try applying the clamp closer to a reinforced section of the hose if available, or consider a different clamping tool if deformation is severe.
Clean the rusted areas with a fine-grit sandpaper or steel wool. Apply a light coat of machine oil to protect the metal surfaces. Store in a dry environment.
Setup: No specific setup is required. The pliers are ready for immediate use upon unboxing. Simply open the handles to engage the clamping mechanism.
Compatibility: These pliers are compatible with most standard rubber and silicone automotive hoses with an outer diameter up to 22 mm (0.87 inches). They are particularly effective for hoses used in cooling systems, fuel delivery (non-high-pressure), and vacuum systems.
Care: To maintain optimal performance and longevity, clean the pliers after each use with a dry or slightly damp cloth. Avoid abrasive cleaners or solvents. Store in a dry place to prevent rust. Periodically check the jaw surfaces for any debris that might affect grip.
