The L and S series refers to metric Din type fittings. Which means light and heavy series. See full answer »

To determine the size of hydraulic fittings you need, you should measure the inside diameter (ID) and outside diameter (OD) of your hoses or tubes, as well as the thread size if applicable. This can be done using a caliper or other measuring tool. This information can be found on https://www.hydraulicsdirect.com/How-..., specifically under the sections "How to Measure Threads" and "Identifying Thread Pitch/Diameter". See full answer »

The standard for hydraulic fittings is typically governed by organizations such as the International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE). Common standards include ISO 8434 for metallic tube connections and SAE J516 for hydraulic hose fittings, which ensure compatibility, reliability, and safety in hydraulic systems. See full answer »

Hydraulic fittings come in various types, including NPT fittings, JIC fittings, ORFS fittings, BSP fittings, Metric fittings, and Flange fittings. Each type has unique characteristics and uses, designed to withstand high pressure, vibrations, and corrosive materials.

The numbers on a hydraulic fitting typically indicate the fitting's size, pressure rating, and thread type. These specifications ensure compatibility and proper function within a hydraulic system by matching the fitting to the corresponding hose or component. See full answer »

A #8 hydraulic fitting typically refers to a 1/2 inch size fitting. This is according to the standard Dash Size system used in the industry to indicate hose and coupling size. See full answer »

To identify different hydraulic fittings, examine key characteristics such as thread type (e.g., NPT, BSP, JIC), size, and sealing method (e.g., O-ring, metal-to-metal). Additionally, using calipers to measure thread diameter and pitch, and referring to manufacturer specifications or fitting identification guides can help ensure accurate identification.

The pressure rating for ORF (O-Ring Face Seal) fittings can vary depending on the specific fitting and material, but they typically can handle pressures up to 6,000 psi (414 bar) for steel fittings and up to 3,000 psi (207 bar) for stainless steel fittings. Always consult the manufacturer's specifications for precise ratings, as they can differ based on design and application. See full answer »

Sure! The maximum pressure for JIC (Joint Industry Council) fittings typically ranges from 1,000 to 5,000 PSI, depending on the size and material of the fitting. It's important to consult the manufacturer's specifications for the exact pressure rating for a specific fitting type and application. See full answer »
