Selecting a cylinder for hydraulics pneumatics work usually comes down to what's doing the pushing and how far you need it to go. The Parker 1" Bore X 2" Stroke Pneumatic Cylinder Series 2A 250 PSI and the 2.5x6 Hydraulic Cylinder from AMRAP Co are both tie-rod cylinders, but they operate in different worlds. The Parker runs on compressed air and lists at $29.95. The AMRAP runs on hydraulic fluid and lists at $126.34. A $96 difference is a signal that these are answers to different jobs, not interchangeable substitutes. To choose between them, you need to think about your existing power source, the stroke length your application requires, and the force you need to move a load.
Quick Verdict
If your project runs on compressed air and only needs light pushing, the Parker is the more practical pick. If you need hydraulic force, the AMRAP is the one to budget for.
Key Differences at a Glance
Here's how the two cylinders line up on the specs that matter.

|---|---|---|
| List price | $29.95 | $126.34 |
| Bore | 1" | 2.5" |
| Stroke | 2" | 6" |
| Cylinder action | Double-acting | Double-acting |
| Cylinder type | Tie-rod | Tie-rod |
| Max pressure | 250 PSI | 2500 PSI |
| Suitable media | Air | Hydraulic fluid |
| Country of origin | United States | India |
| Condition | New - Open box | New |
What to Keep in Mind
If you already have an air compressor and a pneumatics setup, the Parker will drop into that environment with minimal fuss. If your shop runs hydraulic pumps and heavy-duty machinery, the AMRAP is the unit that speaks that language. The choice is less about which is better and more about which matches the system you already have. Also consider the physical space: the AMRAP needs more room to operate because of its size, while the Parker is more compact.
Where Each Product Wins
- Parker: the compact air-powered design suits small fixtures and quick push actions.
- AMRAP: the heavy-duty hydraulic design suits demanding fluid-power jobs.
PARKER 1" Bore X 2" Stroke Pneumatic Cylinder Series 2A 250 PSI
If your shop already has compressed air lines, this Parker cylinder is a natural fit. The design lets it push and pull with air, and the 1" bore keeps the package compact for tight spots. The cylinder is new old stock in an open box. Ports are 1/4" NPT, and the rod threads are male 5/16"-24, so connecting it to standard air fittings is straightforward. The main limitation is the 2" stroke; you won't get much travel out of it. Also, because it's pneumatic, the total force is far lower than a hydraulic cylinder of similar size, so don't expect it to handle heavy pressing or lifting.
2.5x6 Hydraulic Cylinder 2.5" Bore 6" Stroke Double Acting Tie-Rod Cylinder
On the hydraulic side, this AMRAP Co cylinder is rated for 2,500 PSI, which is what gives it serious pushing capability. The 1.125" rod and 12,270 lb column load show the unit is built for heavy work. Retracted length is 16 1/4", extended is 22 1/4", with a 1" pin hole and 3/8" NPT ports. It's made in India. The unit has a black finish. The trade-off is that you need a hydraulic power source; compressed air will not drive this cylinder. Choose it when the job demands real hydraulic force.
Final Choice by Use Case
Choose the Parker if you're setting up an air-powered fixture and need a short, dependable push. Choose the AMRAP if you're building a hydraulic circuit that requires serious pushing force and you're prepared for the larger size and cost.
