The Orbit ORSH is a single-acting, spring-return hollow-center aluminum cylinder. The centre hole lets a rod or cable pass straight through for pulling, tensioning and puller work.
Why aluminum?
- Up to 60% lighter than a comparable steel cylinder, so it's far easier to carry and position, with less back strain
- Hard anodized aluminum resists corrosion and scoring, even with long field use
- Large bearing surface handles unavoidable side loading
- Rated to 10,000 PSI (700 bar) working pressure
- 3/8" high-flow quick-disconnect coupler
- Built and tested to ANSI B30.1
- Made in Vancouver, BC by Orbit Manufacturing
