Hoses, Pipes & Fittings: Hydraulic Hose, Tube, Adaptors and Test Points

Hoses, pipes & fittings carry oil between every pump, valve, cylinder and sensor in a hydraulic system. TSA Hydraulics Engineering supplies hose, tube, adaptors and test points within the Sensors & Switches family of our Motors & Drives range, alongside Pressure Sensors, Temperature Sensors, Flow Sensors and Condition Monitoring.

Most fitting mix-ups come down to threads that look alike. BSP and NPT share the same pitch in some sizes and will start to screw together, then weep or crack the port. JIC and other flare styles cause the same headaches. Send a photo, thread size and hose spec, and we’ll match genuine or equivalent parts

Hydraulic Hose

Wire braid hose (1SN and 2SN types): flexible, for low to high pressure on most machines.
Spiral hose (4SP, 4SH and R13 types): for very high pressure and heavy pressure surges.
Thermoplastic hose: light and flexible, common on lifts and small machines.
Suction and return hose: low pressure and large bore, built not to collapse.

Pressure ratings drop as hose size goes up, so always check the rating for your size, not just the type.

Pipes and Tube

Seamless steel tube: neat, rigid runs on power units and machines, with less expansion than hose.
Stainless tube: for corrosive, marine and food areas.
24° cone compression fittings: the common way to join metric tube.
SAE flanges: for large bore, high flow pump and valve connections.

Use tube for fixed runs, and hose where parts move or vibrate.

Fittings, Adaptors and Test Points

Adaptors join different thread types, such as BSP to JIC or metric to SAE.
Test points let you plug in a gauge or sensor without opening the system.
Sampling valves give a clean point for oil samples.
Quick couplings make connecting and disconnecting tools fast and clean.

Inline adaptors also let you fit flow sensors and temperature probes into existing lines.

Identifying Threads

BSPP (parallel) and BSPT (taper): common in Australia, with a 55° thread angle.
NPT: the American taper thread, with a 60° thread angle.
JIC 37° flare: common on mobile and imported machines.
ORFS (O-ring face seal): very leak resistant, and popular on newer equipment.
Metric 24° cone: used with metric tube and on many European machines.

A thread gauge and a set of callipers solve most identification problems.

Common Leak Points

Mismatched threads forced together.
Taper threads sealed with too much tape, which can crack ports.
O-rings that are reused, pinched or the wrong material for the oil.
Fittings loosened by vibration because the tube runs aren’t clamped.
Over tightened flare fittings with damaged cones.
H2: Hose Safety and Replacement
Pick hose by size, temperature, application, media and pressure.
Route hoses so they don’t rub, twist or bend tighter than their minimum radius.
Replace hoses that are cracked, blistered, kinked or leaking at the crimp.
Never feel for a leak with your hand. A pinhole jet can inject oil through skin.
