The difference between hydraulic hose R1 vs R2 comes down to one thing: R1 is built with a single braided layer of steel wire, and R2 with two. At the most-specified size, -08 (1/2 inch), an SAE 100R1 is rated 16.0 MPa (2,320 psi) and an SAE 100R2 in the same bore 24.0 MPa (3,500

The hydraulic hose pressure rating that governs whether a line is safe to run is its working pressure — the highest pressure the hose is designed to see continuously in normal service. Burst pressure is a different number: it is the destructive test result at which the hose actually ruptures, and SAE J517 requires a

Identifying a hydraulic hose fitting comes down to three measurements and one visual check: thread outside diameter, threads per inch (or metric pitch), whether the thread is straight or tapered, and the shape of the sealing face. Take those four readings and almost all hydraulic hose fittings resolve into one of eight end-connection families —

Hydraulic hose bend radius is the smallest radius a hose can be bent to without kinking, collapsing its bore, or fatiguing the steel reinforcement that carries the pressure. Calculate it in three steps: read the minimum bend radius for your hose type and dash size from the data sheet, convert that radius into the hose

A hydraulic hose layline is the printed line of text and numbers running along the hose cover that identifies its manufacturer, standard, size, working pressure, temperature range, and date of manufacture — and in most cases it is the only reliable way to identify a hose before you replace it. A complete layline carries up

The five hydraulic fitting types you will meet on almost every machine — JIC, ORFS, NPT, BSP, and metric (DIN/ISO) — are separated by two things only: the thread form and the point at which the joint actually seals. JIC seals on a 37° metal flare, ORFS on an O-ring held against a flat face,

Here is the short answer: how to measure hydraulic hose comes down to three separate numbers — overall length, inside diameter (ID), and the end connection. Length is measured end-to-end between the extreme ends of the two couplings, or from sealing face to sealing face when the ends are O-ring face seal, and always through

Knowing how to choose a hydraulic hose comes down to working through seven questions in a fixed order — Size, Temperature, Application, Material/Media, Pressure, Ends, and Delivery — the industry framework known as STAMPED. Answering all seven before you order prevents the most expensive mistake in hydraulics: a hose that satisfies one requirement while quietly

Hydraulic hose sizing converts a required flow rate into a bore diameter the system can live with. Size a line too small and the oil moves too fast: pressure drop rises, the oil heats, and the hose, its fittings, and the pump all age faster. Size it too large and you pay for weight, extra

A thermoplastic fuel hose is a lightweight alternative to rubber for oil and fuel lines: instead of a rubber tube wrapped in steel wire, it uses a polymer tube, synthetic-fibre reinforcement, and a polyurethane cover, which cuts weight by roughly 30-50% at an equivalent pressure rating. The savings show up where rubber is weakest: tight
