- Is this cylinder worth $560.53?
- That depends on the tonnage rating, which is not stated here. At $560.53 from eBay as of November 4, 2026, it is the only new price tracked, so compare it against a named-capacity ram from a known brand before buying.
- What pump do I need for it?
- It is single acting, so it needs a single-acting hand or air pump with a hose that matches the cylinder's port. Confirm the port size and the oil volume the pump can deliver before ordering.
- What is the stroke length?
- The listed heights run from 11.85 in lowered to 19.8 in at maximum, so the stroke is about 8 in. Check that against the lift you need, since the 17.81 cu in oil capacity must fill that stroke.
- What attachments fit the threads?
- The plunger has a 1-8 internal thread 0.75 in deep, and the collar is 2-1/4-14. Standard spreader, wedge and ram accessories in those thread sizes should fit.
- Is it single or double acting?
- It is single acting. The ram extends under pump pressure and returns by load or a spring, so it cannot be powered back in.
- Where can I buy the Value Collection Portable Hydraulic Cylinder Single Acting 17.81 cu in?
