SCHWERLL supplies high-pressure nitrogen hose assemblies for accumulator gas-side connections and nitrogen-charging applications. Manufacturer product information describes multi-layer composite rubber and dedicated materials for high-pressure gas service. Hose bore, length, pressure rating and fitting configuration are confirmed for the selected application.
High-pressure nitrogen hose assemblies are used where flexible connections are required on the gas side of accumulator systems. SCHWERLL manufacturer information identifies die-casting equipment as one application example and describes nitrogen-charging and booster-cart inflation hose contexts.
For this service, gas-pressure hose assemblies differ from liquid-pressure hydraulic hose assemblies. The manufacturer explains that pressurized gas can permeate hydraulic-grade rubber under differential pressure, potentially contributing to bulging, pitting, leakage and, in severe cases, hose-assembly rupture. This describes the stated risk of using hydraulic-grade hose in the documented gas application; it does not establish Post88 compatibility with hydraulic liquids.
Manufacturer information describes Post88 as dedicated high-pressure nitrogen gas hose with multi-layer composite rubber and dedicated materials for high-pressure gas service. The source also describes a rubber surface treatment; it does not specify a puncture-performance or permeation rating.
Fitting structure, sealing configuration and thread type are selected according to the required gas-pressure duty and confirmed for the selected assembly. Manufacturer product information cites DN6, DN10, DN25 and DN32 as commonly used engineering selections; actual nominal bore and availability must be confirmed per configuration.
