What is the pressure rating and compatible hose sizes for the BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel?

BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel . pressure rating and compatible hose sizes: - Pressure rating: Designed for standard heavy-duty hydraulic service; typical working pressure for heavy series crimped fittings of this type is up to 420 bar (â6080 psi). Actual allowable pressure depends on hose type, hose reinforcement, crimp sleeve, and assembly standards; verify with specific hose manufacturer and crimping specifications. - Compatible hose sizes: Intended for metric hydraulic hoses using a crimping sleeve matched to the hose type. Common compatible nominal tube/hose sizes for ZMR112 heavy series fittings are for metric tube/hose IDs in the range of 6 mm to 25 mm (typical sizes: 6, 8, 10, 12, 16, 20, 25 mm). Exact compatible hose ID and corresponding crimp sleeve dimensions must be confirmed from the hose/crimp sleeve manufacturer and the fittingâs detailed size chart. Note: For safe operation, always confirm the exact pressure rating and compatible hose dimensions with the hose and fitting manufacturer datasheets and follow recommended crimping procedures and standards.

How do I properly crimp and inspect the BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel to ensure leak-free assembly?

To properly crimp and inspect the BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel for a leakâfree assembly, follow these steps: 1. Preparations: ensure hose type matches sleeve/crimping profile recommended for BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel. Clean hose and fitting surfaces; remove debris, oil, and damage. Check tube end and locking ring (BES) for visible defects. 2. Assembly: insert hose onto the hydraulic âtailâ fully so the BES locking ring seats correctly. Position the crimping sleeve per manufacturerâs datum marks for BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel. 3. Crimping: use a crimping tool and die set matched to the hose and sleeve. Crimp in one continuous cycle to the specified crimp diameter/profile for the hose and BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel. Avoid partial or multiple incremental crimps unless tool spec allows. 4. Visual inspection: verify uniform crimp profile, no cracks, splits or flattened areas. Ensure BES locking ring is not deformed and remains seated. Check coating integrity (zincânickel) for obvious damage. 5. Dimensional check: measure finished crimp diameter and compare with specification for BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel. 6. Pressure/leak test: perform a pressure test at or above system working pressure (per hose/fitting specs) and inspect for leaks for the required duration. 7. Documentation & rejection: record crimp parameters, die used, operator, and test results. Reject assemblies with uneven crimps, exposed reinforcement, loose locking ring, or leakage. Following these steps ensures a reliable, leakâfree assembly of BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel.

Can BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel be used with synthetic hydraulic fluids and seals?

Generally no. proceed with caution and verify compatibility before use. Explanation: BES metric tube end, type ZMR112, heavy series, carbon steel, zinc-nickel is a standard hydraulic tail fitting for crimped hoses, made of carbon steel with a 6â10 Âµm zincânickel coating that gives excellent corrosion resistance. The key compatibility concerns with synthetic hydraulic fluids are the elastomer/material compatibility of the hose and seals, and the chemical resistance of any coatings or base metals. - Seals: The product description specifies sealing with a locking ring (BES). The compatibility of the sealing system depends on the seal material (e.g., NBR, FKM, HNBR, PTFE). Some synthetic fluids (esters, polyalphaolefins, phosphate esters) attack certain elastomers. You must confirm the seal elastomer grade used in your hose assembly is compatible with the specific synthetic fluid. - Hose/crimp: The ZMR112 is intended for crimping with a sleeve matched to the hose type. Ensure the hose inner tube and cover are rated for the chosen synthetic fluid and operating temperature/pressure. - Metal and coating: Carbon steel with zincânickel plating is generally resistant to corrosion and is compatible with most hydraulic fluids. However, some aggressive fluids (especially certain fireâresistant fluids or highly polar synthetic esters) can have additives that may affect coatings or cause galvanic interactions in specific environments. The zincânickel layer itself is not typically a limiting factor for fluid compatibility but verify with the fluid and coating suppliers if concerns exist. Recommendation: Do not assume universal compatibility. Confirm all three elements before use: 1) Identify the exact synthetic hydraulic fluid (type, additives, temperature range). 2) Verify the seal elastomer material used in the hose assembly is compatible with that fluid. 3) Confirm the hose inner tube and crimp sleeve are approved for that fluid and operating conditions. If in doubt, consult the hose/seal manufacturer or material safety/data sheets and perform compatibility tests.
