Thumbnail Filmstrip of 65-253 | 1/2" NPT Female Tee Images
Our NPT Malleable Black Iron fittings are made with care and attention to detail. Reduced parting lines and smoother edges result in better fluid flow. By using a low
temperature galvanizing process the coating is more durable which means a longer
lasting fitting. All Fittings are 100% Pressure Tested to 300# Class.

SAE 100 R2 is a specification for a type of high-pressure hydraulic hose characterized by its two layers of steel wire braid reinforcement. It is designed for use with petroleum-based hydraulic fluids and operates within a temperature range of -40°C to +100°C, with pressure ratings varying according to hose size, typically ranging from 4,000 to 6,000 psi.
SAE 100R2AT is a specification for hydraulic hoses set by the Society of Automotive Engineers (SAE). It indicates a hose with two layers of braided steel wire reinforcement, suitable for high-pressure applications, and typically used in hydraulic systems. The "AT" denotes that the hose meets additional performance requirements for impulse testing.
SAE 100 R2AT is a specification for high-pressure, two-wire braided hydraulic hoses. These hoses are designed to withstand higher pressures and are commonly used in hydraulic systems for industrial and agricultural machinery. They feature an oil-resistant synthetic rubber inner tube, two layers of steel wire braid reinforcement, and an abrasion-resistant synthetic rubber outer cover.
To specify a hydraulic hose, you need to consider key factors such as the hose size (inner diameter), pressure rating, temperature range, compatibility with the hydraulic fluid, and the type of fittings required. Additionally, you should refer to relevant standards like SAE, ISO, or DIN to ensure the hose meets the necessary performance and safety criteria for your application.
Hydraulic hose is typically measured by its Inner Diameter (ID). This measurement is important because it determines the flow velocity of the hydraulic fluid within the hose. Source: 1.

(See under "Hose Bore size" section).
Yes, the size of a hydraulic hose significantly affects flow. Larger diameter hoses can carry more fluid, reducing resistance and pressure loss, which can improve system efficiency. Conversely, smaller diameter hoses can restrict flow, leading to increased pressure drop and potentially reduced system performance.
SAE 100 R1 hose is a type of hydraulic hose that meets the specifications set by the Society of Automotive Engineers (SAE). It features a single layer of steel wire braid reinforcement, making it suitable for medium-pressure hydraulic applications. This hose is commonly used in industrial and mobile equipment for conveying hydraulic fluids.
To identify your hose, check for any labels or markings on the hose itself, which often include manufacturer details, model numbers, and specifications like diameter and length. Additionally, you can compare the hose's connectors and dimensions with standard hose types or consult the user manual or manufacturer’s website for more information.
