Types of Hydraulic Hose Explained: Uses, Construction & Selection

Leave a Comment / Blog / By

The main types of hydraulic hose fall into six construction families — single-wire braid, double-wire braid, spiral-wound, textile braid, thermoplastic, and PTFE — and which one belongs on a given line is decided by four numbers: working pressure, bore size, fluid temperature, and bend radius. This guide gives you the chart and the checklist together: […]

An oilfield hose is a flexible, wire-reinforced line built to carry drilling fluid, cement, fracturing fluid, or well-control fluid under pressure. The working pressure depends on the duty: a rotary drilling or vibrator hose is specified from about 4,000 psi to 7,500 psi (Grade C to Grade E), a fracturing hose commonly works at 10,000–15,000

Hydraulic Hose Temperature Rating: Limits, Charts & Selection

Leave a Comment / Blog / By

A hydraulic hose temperature rating is the range of fluid temperatures a hose is designed to carry continuously — for standard rubber hydraulic hose, -40°C to +100°C (-40°F to +212°F), with an intermittent allowance that usually stops around +120°C (+248°F). The three limits people search for most often are these: standard rubber hose -40°C to

Hydraulic Hose Pressure Rating: Working vs Burst Pressure

Leave a Comment / Blog / By

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

Hydraulic Hose Fittings: The Ultimate Guide to Identification & Selection

Leave a Comment / Blog / By

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: How to Calculate & Why It Matters

Leave a Comment / Blog / By

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
