FAQ
Q1: What is the difference between a 1-wire and a 2-wire hydraulic hose?
A: The number refers to the layers of steel wire braid reinforcement. A 3 8 2 wire hydraulic hose has two layers, offering higher working and burst pressure ratings compared to a 1-wire (SAE 100R1) hose of the same size. It is designed for more demanding, higher-pressure applications.
Q2: Can this hose be used with water-based fluids (HFA, HFB)?
A: Standard SAE 100R2AT hoses with standard tube compounds are primarily for oil-based fluids. For water-based fluids (hydraulic water glycols), a specific tube compound is required. Please consult our technical team for the correct hose specification for your fluid type.
Q3: How do I properly select and assemble this hose?
A: Correct selection involves matching the hose's working pressure to your system's maximum operating pressure with a safety margin. Assembly requires compatible, crimped SAE 100R2AT fittings and a professional crimping machine to ensure a leak-proof, safe connection. We can supply pre-made assemblies or the components and guidance for your workshop.
Q4: What is your standard packaging for export?
A: We typically pack hoses in coil form in sturdy cardboard boxes or on wooden reels for longer lengths, protected with plastic wrapping. All packaging is designed to withstand long-distance shipping. Specific packaging can be customized upon request.
Q5: Do you offer custom hose assemblies?
A: Yes. We provide a complete service, manufacturing custom-length 3/8" 2 wire hydraulic hose assemblies with a wide range of fitting types (JIC, NPT, BSP, etc.) to your precise specifications, ready for installation.
