Professional Hydraulic Cylinder Seal Installation Tools Kit
- EASY TO MAKE AN Ω SHAPE: Rod seal install tool set for the quick, safe installation of flexible rod seals. 3 sizes are included for various rod seal installation jobs from 0.87" and up.
- LARGE HANDLE & ANTI-SLIP DESIGN for EASY USE: The Hummingbird Seal Twistor's handle design may help users grab the twistor with ease and comfort no matter whether they're wearing gloves. It also features an anti-slip property. The handle with a user-friendly angle design can aid in reducing wrist strain and making it easier to use. It also features a hollow-out area that is simple to hang in your workspace at any time and place.
- 360 DEGREE PROTECTION: We want to preserve your hydraulic cylinder and seal. As a result, we created the round-nosed design with the intent of avoiding scuffing the seal o-ring and cylinder chamber. Polycarbonate was used to make it since we want you to have a product that is both strong, stiff, and lightweight. It can even be utilized on different material-type hydraulic cylinders like ceramic.
- AS YOU DESIRE: The Hummingbird Seal Twistor set includes three pieces that may be used for a range of seal sizes. Small hummingbirds can work on a size-bore 0.87" - 1.57" (22-40mm) seal with a maximum 6mm cross-section. Medium hummingbirds can work on a size-bore 1.57" - 2.75" (40-70mm) seal with a maximum 8mm cross-section. Large hummingbirds can work on a size-bore 2.75" - 6.49" (70-165mm) seal with a maximum 10mm cross-section.

FAQs

How does the "Seal Twister" tool work, and how does it prevent damage to expensive hydraulic seals?
This tool is a game-changer for hydraulic repairs. It safely bends the U-cup or rod seal into an $\Omega$-shape (omega shape) without leaving sharp creases. This temporary reduction in size allows you to effortlessly slip the seal into the deep gland groove of the cylinder. By eliminating the need for sharp screwdrivers or makeshift tools, it completely prevents accidental scratches, tears, or damage to both the seal and the cylinder wall.
What sizes of seals can this 3-piece kit handle, and is it suitable for heavy equipment?
Yes, this universal 3-piece kit is specifically designed to cover the vast majority of automotive, industrial, and heavy equipment hydraulic repairs (such as excavators, loaders, and backhoes). The kit includes three color-coded sizes to handle a wide range of rod diameters:
- Small (S): For rod diameters from 22mm to 40mm (0.87" - 1.57") with a max seal cross-section of 6mm.
- Medium (M): For rod diameters from 40mm to 70mm (1.57" - 2.75") with a max seal cross-section of 8mm.
- Large (L): For rod diameters from 70mm to 165mm (2.75" - 6.49") with a max seal cross-section of 10mm.
How does the upgraded handle design make installation easier compared to standard versions?
Bending heavy-duty, high-hardness hydraulic seals requires significant hand strength. Our upgraded kit features an extra-large, heavy-duty handle design that provides superior leverage, making it much easier to twist stiff seals. Additionally, the handles are equipped with a premium anti-slip thumb grip feature, giving you maximum control and safety even when your hands are slick with hydraulic oil or grease.
