What Stands Out
Durable Material
Constructed from 6061 aluminum, this valve release knob offers exceptional strength and longevity, ensuring reliable performance under pressure while resisting corrosion and wear over time.
Perfect Fit
Designed specifically for Harbor Freight's Hydraulic Press and bottle jacks, this knob seamlessly replaces old or damaged handles, providing an easy and efficient solution for enhancing your lifting equipment.
Easy Installation
The straightforward design allows for quick and hassle-free installation, enabling users to effortlessly replace their valve release knob without specialized tools, saving time and improving operational efficiency.
Product Details
- HIGH QUALITY MATERIAL: This release knob is made of high quality aluminium, high hardness, strong bearing capacity, not easy to deform, and the surface is corrosion-resistant, long service life.
- UNIQUE DESIGN: This jack release knob can perfectly replace the jack handle lever. No need to disassemble the jack handle on the plunger/pivot assembly to release the jack every time.
- EASY TO GRIP: The knob has a printed surface for better feel and grip. Friction is also good for preventing slippage caused by sweaty hands.
- EASY TO INSTALL: Slide the jack valve knob onto the jack release screw and turn 1/4 turn to snap it into place. Then use a 5/32 hex spanner to install the set screw to the end of the knob and tighten for security.
- COMPATIBILITY: Can be used on 6, 12 and 20 tonne presses as well as any bottle jack with a 7/16 inch diameter as a pressure release knob.
