Core Features & Technical Advantages

Heavy-Duty Dual-Braid Reinforcement for Maximum Pressure Capacity

The defining feature of our SAE 100R2AT high pressure hydraulic hose is its dual-layer high-tensile steel wire braid reinforcement, engineered to handle extreme working pressures ranging from 78 bar (1131 psi) for the 2" diameter up to 350 bar (5075 psi) for 3/16" and 1/4" sizes. This dual-braid structure distributes pressure evenly across the hose body, resisting deformation, bulging, and failure even under repeated pressure surges common in heavy construction and industrial hydraulic circuits. The seamless oil-resistant synthetic rubber inner tube ensures exceptional fluid compatibility, preventing leaks, fluid degradation, and internal wear over thousands of operating hours, while the rugged outer cover provides a protective barrier against physical damage and environmental exposure.

Industry-Leading Safety Margins for Reliable Operation

Safety is a top priority for commercial heavy equipment operations, and this double steel wire braid hydraulic hose is built with conservative, industry-validated safety factors to mitigate operational risk. It delivers a consistent 4:1 burst pressure to working pressure ratio across all sizes, with burst pressures reaching up to 1400 bar for the smallest diameters, and a 2:1 proof pressure ratio for pre-installation performance testing. These safety margins provide critical protection against unexpected pressure spikes, shock loads, and vibration in heavy construction equipment, reducing the risk of catastrophic hose failure and unplanned downtime on job sites.

Balanced Flexibility for Compact Equipment Routing

Despite its heavy-duty high-pressure design, our SAE 100R2AT thermoplastic hydraulic hose maintains exceptional flexibility for tight routing in compact equipment spaces. It features size-specific minimum bend radii, ranging from 100 mm for 3/16" and 1/4" sizes up to 630 mm for the 2" diameter. This flexibility allows for easy installation around tight equipment frames, engine compartments, and implement connections on construction machinery, without compromising pressure performance or structural integrity. Adhering to the minimum bend radius guidelines prevents kinking, internal tube damage, and stress on the dual steel braids, extending the service life of the hose in continuous heavy-use applications.

Applications & Industry Use Cases

Heavy Construction & Off-Highway Equipment

This SAE 100R2AT hydraulic hose for construction equipment is purpose-built for the most demanding off-highway and construction applications. It is the ideal solution for excavators, loaders, bulldozers, cranes, and other heavy construction machinery, where it handles high-pressure hydraulic fluid transfer for lifting, digging, steering, and implement operation. Its abrasion and weather resistance make it perfect for continuous outdoor use on job sites, withstanding exposure to dust, debris, mud, and extreme temperature fluctuations.

Industrial Machine Tool & High-Pressure Hydraulic Systems

Beyond construction applications, this hose excels in stationary industrial high-pressure hydraulic systems, machine tool operations, and heavy-duty agricultural equipment with high-pressure hydraulic circuits. It is fully compatible with a wide range of industrial fluids, including petroleum-based hydraulic oils, water-based hydraulic fluids, and lubrication oils, making it a versatile choice for production facilities, manufacturing plants, and commercial maintenance operations. Its strict adherence to SAE 100R2AT standards makes it a trusted OEM specification and replacement part for heavy equipment manufacturers worldwide.

FAQ

Q1:Why is this listed as a thermoplastic hydraulic hose, and what does that mean for performance?

A1:

Although titled "Thermoplastic," this SAE 100R2AT hose uses an oil-resistant synthetic rubber inner tube, two high-tensile steel wire braids for reinforcement, and an oil/abrasion/weather-resistant synthetic rubber cover. The "thermoplastic" reference likely highlights enhanced material properties in some contexts, but the core design delivers high-pressure performance (e.g., 5075 PSI WP for 3/16"–1/4" sizes) with excellent flexibility and durability for petroleum or water-based fluids. It provides robust sealing and media compatibility similar to traditional rubber hoses while meeting SAE 100R2AT standards.

Q2:What high-pressure capabilities does the double steel wire braid provide, and how does burst pressure factor in?

A2:

The two layers of high-tensile steel wire braids enable high working pressures from 1131 PSI (78 bar) for 2" up to 5075 PSI (350 bar) for smaller sizes like 3/16" and 1/4". Burst pressure is consistently 4:1 safety ratio (e.g., 1400 bar for 3/16"–1/4", 980 bar for 1/2"), and proof pressure is 2× WP (e.g., 700 bar for smaller sizes). This makes it suitable for demanding high-pressure hydraulic oil lines in construction equipment, machine tools, and agricultural machinery.

Q3:How does the bend radius affect routing in tight equipment spaces?

A3:

Minimum bend radius varies by size for safe, kink-free installation (e.g., 100 mm for 3/16"–1/4", 180 mm for 1/2", 300 mm for 1", up to 630 mm for 2"). Staying within these limits prevents internal damage to the synthetic rubber tube or stress on the double braids. For compact machinery like agricultural implements or machine tools, choose smaller diameters (e.g., 3/8" at 130 mm Min.B.R.) to allow tighter routing without compromising the 4060 PSI (280 bar) working pressure.

Q4:What makes this hose suitable for petroleum and water-based fluids in outdoor or industrial environments?

A4:

The oil-resistant synthetic rubber inner tube ensures compatibility with petroleum-based hydraulic fluids, while the outer cover resists oil, abrasion, and weather—ideal for exposed applications in construction sites, agricultural fields, or machine tool operations. It handles temperatures from -40°C to +121°C and supports both petroleum and water-based fluids without degradation, providing reliable performance in varied industrial conditions.
