The hose is the component people economise on and it is the one most likely to hurt somebody. At 700 bar a failed hose releases a great deal of energy very suddenly, and a pinhole leak produces a jet fine enough to penetrate skin — hydraulic injection injuries are a surgical emergency and are frequently underestimated because the entry wound looks trivial.
Three lengths are available, in 700 bar and 1000 bar ratings. **Match the rating to your system**: a 700 bar hose must never be used on a 1000 bar circuit, and every component — pump, hose, coupler, gauge, cylinder — must be rated to the highest pressure the system can generate.
Key Features
- Three lengths: 1.8 m, 2.0 m and 3.0 m, to suit the working distance between pump and cylinder.
- Two pressure ratings: 700 bar on the 1.8 m and 3.0 m, 1000 bar on the 2.0 m. Check which your system needs.
- Matched to the Tecpos range: Designed to work with the ESP and THPA pumps and TSSC cylinders.
- Certification available to 2.1.

High pressure hydraulic hose. Every component in a hydraulic system must be rated to the highest pressure the system can generate. Never fit a 700 bar hose to a 1000 bar circuit. Hydraulic fluid injection is a surgical emergency; never search for a leak by hand.
Suitable Applications
Connects Tecpos hand pumps to cylinders in hydraulic lifting, jacking, pressing and pulling applications. Length is chosen by the working distance required between the pump position and the cylinder — far enough that the operator is clear of the load, short enough that the hose is not lying where it can be damaged or tripped over.
More About This Product
Manifolds, valves and gauges are the components that turn a pump and a cylinder into something controllable. Without them you have force; with them you have a lift that can be held, isolated, adjusted and measured.
They are also the components most often mismatched. A pump and a cylinder get bought together and rated correctly; the valve block comes out of a drawer, and nobody checks what it is rated to.
Multi-Point Lifting and Why the Gauge Is Not Optional
Lifting at several points at once is what manifolds exist for. Lifting a long or heavy item at a single point twists it, and on machinery or structures that twist is often more damaging than the lift itself. A manifold splits one pump output across several cylinders so the load rises evenly.
That introduces its own discipline. Cylinders on a shared circuit see the same pressure but not necessarily the same load, and a cylinder taking less than its share is doing nothing while its neighbours take more. Individual isolation valves let each leg be adjusted, which is why they are worth having.
The gauge is the part people leave off and should not. On a proof test the pressure reading is the measurement — without it you cannot state what load was applied. On a controlled lift it is the only indication that the system is behaving: a pressure that climbs when nothing is moving means something is binding, and a pressure that falls when nothing is being released means a leak.
Injected hydraulic fluid is a surgical emergency. At 700 bar a pinhole leak produces a jet that penetrates skin without the operator necessarily feeling it as more than a sting, and the fluid then causes tissue damage that develops over hours. The entry wound looks trivial and the injury is not. Anyone who suspects fluid injection needs a hospital immediately and needs to say what fluid it was. This is why leaks are located with a piece of cardboard and never with a hand.
How to Use the Hose
- Match the pressure rating to the system: Never fit a lower rated hose than the system can generate.
- Check couplers match: The TSSC cylinders use TBC 381F (PT3/8).
- Route the hose clear: Away from sharp edges, heat, moving parts and foot traffic.
- Do not kink or bend tightly: A kinked hose fails at the kink.
- Bleed air before working: Air gives a spongy action and unpredictable movement.
- Never search for a leak by hand: Use cardboard or paper. Injected fluid is a surgical emergency.
Warning: Hydraulic fluid injected under the skin is a surgical emergency and requires immediate hospital treatment, even though the entry wound may look minor. Never search for a leak with your hand. Never use a hose rated below the system pressure.
Safety Information
- Every component must be rated to the system's maximum pressure.
- Never search for a hydraulic leak by hand.
- Route hoses clear of edges, heat, moving parts and foot traffic.
- Do not kink, twist or bend tightly.
- Withdraw any hose showing abrasion, bulging, kinking, exposed reinforcement or leakage.
- Check couplers are fully engaged before pressurising.
- Depressurise before disconnecting.
- Inspect before every use.
Inspection and Maintenance
Inspect the full length before every use. Look for abrasion through the outer cover, any bulging under pressure, kinks, crushing, and above all exposed reinforcement — a high pressure hose showing braid has failed its outer protection and must be withdrawn immediately. Check both end fittings for leakage, corrosion and security, and the couplers for damage and full engagement. Store hoses coiled loosely rather than tightly, since repeated tight coiling creates permanent kinks at the same points.

Frequently Asked Questions
Q: Why is the 2m hose more expensive than the 3m?
The 2 m is rated to 1000 bar where the 1.8 m and 3.0 m are 700 bar. You are paying for the pressure rating, not the length. Check which your system requires before choosing on price.
Q: Can I use a 700 bar hose on a 700 bar pump?
Yes, that is the matched rating. What you must not do is use a hose rated below any pressure the system can generate, and you should confirm every other component — couplers, gauge, cylinder — carries the same rating.
Q: What is a hydraulic injection injury?
A pinhole leak at high pressure produces a jet fine enough to penetrate skin without an obvious wound. The fluid spreads through the tissue and causes serious damage. It is a surgical emergency requiring immediate hospital treatment, and it is why you never check for a leak by hand.
