The right oil transfer hose is chosen by matching five specifications — inner diameter, working pressure, temperature range, end fittings, and construction (suction, discharge, or both) — to the fluid, flow rate, and duty of the line. This guide walks through every step of oil hose selection in order, provides the size chart and pressure […]

An oil suction and discharge hose is a flexible rubber hose engineered to move petroleum products such as diesel, fuel oil, lubricating oil, and mineral oil under both suction (vacuum) and discharge (pressure) conditions, commonly built to EN 1765 or DIN 20023 in 10 bar and 20 bar working pressure classes, with sizes from 3/4

If you are choosing an oil resistant hose for hydraulic, fuel, suction, or transfer service, the answer starts with one material decision: nitrile (NBR) rubber is the industry-standard tube for oil contact, with the right cover compound and reinforcement. Oil resistance is a measured property, not a marketing claim — ASTM D471 immersion testing rates

Oil hose working pressure is the maximum internal pressure an oil hose can carry continuously and safely at its rated temperature, while burst pressure is the destructive-test pressure at which the hose ruptures — and for most oil hoses the two are separated by a 4:1 safety factor, meaning the minimum burst pressure is four

An oil hose is a flexible rubber or thermoplastic tube engineered to carry petroleum-based fluids — hydraulic oil, lubricating oil, engine oil, and diesel fuel — without swelling, softening, or shedding particles into the fluid. This guide explains the main oil hose types, the industries and machines that use each one, and the selection steps

A hydraulic hose is a flexible, reinforced tube that carries pressurized hydraulic fluid between pumps, valves, and actuators to transmit power in machines of every size. If you are replacing a blown line on an excavator, specifying hoses for a new machine, or sourcing for a fleet, this guide covers construction, types, sizes, pressure ratings,

The right hydraulic oil hose for your system is selected by matching five numbers — bore size, working pressure, temperature range, minimum bend radius, and end fitting type — then confirming the construction family (SAE 100R1, 100R2, or spiral-wound) against your fluid and duty cycle. This guide walks through every step of hydraulic hose selection

Looking for the right excavator hydraulic hose for your boom lines? The short answer: match the working pressure to your machine’s relief valve setting (4,000–5,800 PSI on standard excavators), choose two-wire braid (SAE 100R2) for mini and mid-size machines or four-spiral (100R12) above 30 tons, and match the fitting thread to your machine brand —

The 2 wire vs 4 wire hydraulic hose question has one practical answer: choose a 2-wire braid hose when your system runs at or below 4,000 PSI with moderate impulse cycles, and choose a 4-wire spiral hose when pressure spikes exceed 4,000 PSI or the circuit sees constant, violent pressure pulses. The number of steel wire

Cover. Measure the open bore with a caliper — the air hose size is the inside diameter. Air hose size is the inside diameter (ID) of the bore — the passage compressed air actually flows through — always expressed by the bore, in fractions of an inch or in dash sizes. Quick answer: measure the open bore
