VERSO Multiflex and Compact Wire-Braided Hydraulic Hoses

VERSO 1SN, 2SN Multiflex and 1SC, 2SC Compact hydraulic hoses are designed for intermediate pressure lines on agricultural tractors, machine tools, and forklifts. Thanks to reduced bend radii, Compact 2SC lines streamline routing in tight compartments and reduce total assembly weight.

One or two high-tensile steel wire braids: balanced flexibility with high burst strength
Reduced bend radius Compact configuration: effortless installation in confined spaces
Weather and ozone resistant outer rubber cover: protects reinforcement from degradation
Working pressure ratings up to 250 bar: versatile operation in mobile machine systems

VERSO Hydraulic Fittings, Adapters, and Quick Release Couplings

VERSO fluid connector lines feature DIN 2353 24° cone tube fittings, JIC 37° flared adapters, and ISO 16028 Flat Face quick release couplings. These engineered components ensure leak-tight integration between rigid steel tubing and flexible hydraulic hose lines across fluid circuits.

Metric 24° cone light L and heavy S series: dual-edge cutting ring for positive bite
Flat Face dry-break quick couplings: prevents fluid dripping during line disconnection
Protective zinc electroplating: exceeds 400 hours salt spray corrosion resistance
Precision machined BSP, NPTF, and Metric threads: secure torque retention under vibration

VERSO PTFE and Thermoplastic High-Performance Hoses

VERSO specialty fluid conduits incorporate PTFE 1SS and 2SS hoses shielded by stainless steel braid, alongside R7 and R8 thermoplastic lines. Chemically inert, these hoses handle aggressive solvents, refrigerants, and compressed gases within a temperature span from -70 °C to +260 °C.

Virgin fluoropolymer core tube: smooth or corrugated profiles for flexible routing
Stainless steel wire braid AISI 304: structural reinforcement against pressure surges
Thermoplastic polyamide R7 and R8 lines: non-conductive options for mobile aerial lifts
Universal chemical resistance: handles industrial solvents, glues, gases, and steam

VERSO Hose Crimping Machinery, Cutters, and Workshop Tools

VERSO workshop equipment portfolio features hydraulic crimping machines delivering up to 300 tons of pressing force, hose cutting saws, skiving units, and uncoiling tables. These tools guarantee precise radial swaging of ferrules on high-pressure hoses up to 2 inches in diameter.

Radial crimping head with micrometer dial: swaging accuracy calibrated within 0.05 mm
Quick-change die sets: swift tool changeover across full industrial diameter spectra
Hose cutting saws with scalloped blades: smooth cut without scorching rubber compound
Dual skiving heads: precise external and internal rubber removal for Interlock fittings

Engineering Architecture of VERSO Hardex R15 Multi-Spiral Hoses

VERSO Hardex R15 multi-spiral hydraulic hoses are designed in compliance with SAE 100 R15 criteria for severe fluid circuits subjected to extreme impulse loading.

Unlike standard wire-braided hoses where wires cross each other, the Hardex construction incorporates four or six alternating spiral layers of high-tensile brass-plated steel wire.

This multi-spiral architecture prevents wire-to-wire friction during hydraulic pressure spikes up to 420 bar, eliminating fatigue failure of the reinforcement core.

The inner tube of synthetic elastomer offers resistance against oxidation and high temperatures under continuous hydraulic oil circulation.

Selection Guidelines for VRSVS-R1525 Heavy Hydraulic Assemblies

Reinforced lines of the VERSO VRSVS-R1525-STD-F series in DN38 nominal bore size with six spiral steel plies are engineered to deliver high fluid flow volume in main hydraulic pump and motor circuits.

When routing heavy hydraulic lines, machine engineers must evaluate both working pressures and dynamic impulse peaks generated during rapid control valve shifts.

The VRSVS-R1525 hose line maintains a compact bend radius, minimizing mechanical bending stress in the rubber matrix around mobile boom articulated joints on mining excavators. The synthetic rubber cover protects internal spirals against quarry dust, sunlight UV, and oils.

Assembly Principles of DIN 2353 24° Cone Metric Tube Fittings

VERSO metric tube fittings with a 24-degree cone adhering to DIN 2353 standards provide leak-free mechanical joins between rigid seamless hydraulic steel tubes and distribution manifolds.

As the retaining nut is tightened, the cutting ring with dual cutting edges bites into the outer tube perimeter, creating a solid retention ridge and metal-to-metal seal.

This connection technique eliminates on-site welding, withstands high vibration, and permits repeated disassembly during regular machine servicing. For elevated working pressures, heavy series S fittings feature thicker tube walls and reinforced threads for dependable service.

Operational Advantages of ISO 16028 Flat Face Quick Release Couplings

VERSO Flat Face quick release couplings designed to ISO 16028 standards prevent oil spillage and eliminate air ingress when connecting auxiliary hydraulic attachments.

The flush-face interface allows machine operators to wipe mating surfaces clean with a shop cloth prior to coupling, safeguarding hydraulic reservoirs from abrasive soil contaminants.

An integrated safety sleeve locking ball arrangement prevents accidental uncoupling when lines strike obstacles during excavator trenching. Rated for pressures up to 350 bar, Flat Face couplings minimize circuit pressure drop through flow-optimized internal fluid geometry.

Application of Chemically Inert PTFE and Thermoplastic Hoses

VERSO PTFE flexible conduits with smooth or corrugated fluoropolymer cores and AISI 304 stainless steel exterior wire braiding excel in circuits conveying aggressive chemical media and high-pressure steam.

Fluoropolymer provides chemical inertness to industrial acids, alkalis, polyurethane adhesives, solvents, and refrigerants without age hardening over prolonged service.

Complementing them, R7 and R8 thermoplastic polyamide lines reinforced with high-modulus synthetic fiber offer non-conductive electrical properties for mobile aerial work platforms. The core maintains flexibility from -70 °C to +260 °C.

Precision Swaging Protocol and Crimp Diameter Inspection

Swaging hydraulic couplings onto VERSO hose lines requires strict adherence to calibrated radial crimp diameters published in technical specification sheets.

For four- and six-spiral Hardex R15 lines, technicians must perform external and internal rubber skiving on specialized workshop preparation machinery prior to fitting insertion.

Skiving exposes the steel reinforcement to exact depth, enabling the Interlock coupling teeth to grip spiral plies directly without slippage under peak pressures. Following crimping, operators verify finished sleeve outer diameters across three radial planes using vernier calipers.
