Liquefied Gas Low-pressure 1.2 Pressure: Tonnage, Reach and Access
Liquefied Gas Low-pressure 1.2 Pressure are described by numbers that all look similar on a listing and behave very differently in use. Sorting out which of them actually matters is what this page sets out to do.
Prices here start at $8.99 and reach $10.31 across 2 options. Where the step between two options is small, the difference is usually a size; where it is large, the specification has changed.
The range at a glance
Starting with the whole range rather than the first option makes the rest of the page much quicker to read, because the size of the choice is visible from the outset.
| Item | This listing | What it tells you |
|---|---|---|
| Options available | 2 options | Each option is priced separately |
| Price band | $8.99 to $10.31 | The step between options is the specification change |
| Size or capacity span | Not set by size | The choice is by material and finish rather than size |
| Units used in the options | Mixed | The units you will be comparing against the job |
| Format | Variable product | How the options are structured on the site |
Sizing it to the job
Sizing is where most purchases are won or lost, and it is decided by the job rather than by the catalogue.
| Dimension | What it decides | How to choose |
|---|---|---|
| Rated tonnage | The force the tool develops at working pressure | Sized to the part, with the pump matched |
| Reach and opening | What the tool gets behind and how far it spreads | Judged on the tightest access, not the easiest |
| Power source | Manual, integral or separate pump station | Split systems for remote or high-cycle work |

What to check when it arrives
Nothing here takes more than a minute, and each row corresponds to a fault that is far cheaper to find now than after the first job.
| Check | Why it matters | What good looks like |
|---|---|---|
| Jaws or spreader tips are forged | Cast components crack at the point of load | A forged or alloy working end |
| Forcing screw is centred and true | An off-centre screw bends jaws instead of moving parts | A screw that runs true by hand |
| Hoses and couplers are rated | The hose carries the same pressure as the tool | Rated hose with clean, undamaged couplers |
| Gauge or relief valve is fitted | It is what stops an overload becoming a failure | A relief valve or a readable pressure gauge |
| Accessories match the parts you pull | Jaws and plates decide the result more than tonnage | The right jaw set for the bearing or flange |
| Seal kits are available | Seals are the first thing to fail | A stocked seal or repair kit |
Where these go wrong
These are the failures worth knowing before they happen, because the early sign is always cheaper to act on than the late one.
| Symptom | Likely cause | What to do |
|---|---|---|
| Part will not move at full tonnage | Screw off centre, or the load is beyond the tool | Re-centre the tool, then add heat rather than force |
| Jaw tip cracks or spreads | Point loading on a cast jaw or an overload | Replace the jaw and reduce the tonnage applied |
| Ram creeps back under load | Seal wear or a leaking coupler | Check the coupler first, then the seal kit |
| Pump will not hold pressure | Air in the system or a relief valve set low | Bleed the system and check the valve setting |
Hydraulic tools in practice
Hydraulic tools trade access for force. A tool that reaches the part and stays square will move it at a fraction of the tonnage a badly aimed one needs.
Force ratings are per tool, not per joint. The tonnage figure tells you what the tool can develop; the jaw, the spreader or the ram decides how much of that force actually lands on the part.
Hydraulic gear is quiet, which is why overloads go unnoticed. Working above the rating loads the seals and the frame every time, and the damage appears later as a leak or a cracked jaw.
Ordering for a team or a season
Past a single unit the question stops being which option and becomes how many, and the answer comes from consumption rather than from the price list.
Quoting works on quantity, so it pays to give the number required and the date it is needed together instead of asking for a unit figure and negotiating afterwards.
Frequently Asked Questions
A short set of answers to the questions buyers ask most often about liquefied gas low-pressure 1.2 pressure.
How do I choose the tonnage?
From the part and the fit, not from a catalogue maximum. A tool that reaches the part squarely moves it at a lower tonnage, so access usually decides the model and the tonnage only has to cover the worst case.
When should I use heat instead of force?
When the tool reaches its rating and the part has not moved. Warming the housing evenly, never the shaft, is usually kinder to the bearing and safer for the tool than adding tonnage.
Manual or a separate pump station?
Manual for occasional work in accessible places, split systems where the tool goes somewhere a hand cannot stay, or where the cycle repeats all day.
What fails first?
Seals and jaw tips. Both are cheap, both are replaceable, and both are worth keeping on the shelf so a leak does not stop a job.
Why does the tool work better on one job than another?
Access and alignment. The same tool that walks a bearing off a clean shaft will struggle on a corroded one, because the force is going into friction rather than movement.
Keeping it working
The routines below are short because the failures that matter are few, predictable and easy to prevent.
- Oil the forcing screw before every pull; a dry thread doubles the effort.
- Inspect jaw tips after each heavy pull for cracks and deformation.
- Keep hoses off the floor and couplers capped when not in use.
- Store with the ram retracted and the screw wound in.
- Change hydraulic oil at the maker’s interval and bleed afterwards.
- Never leave a tool standing loaded overnight.
