Parker Industrial Hose Catalog 4800 - MRO Stop

ecommended.• Do not use LPG hose for fuel hose in vehiclesusing CNG (Compressed Natural Gas).• The hose used with Natural Gas should besubjected to the same rigorous tests andinspection as if it were being used with LPG.Contact Parker for specific hose recommendations.Welding Hose: Due to the extreme volatility of gases andthe rough environment of many welding applications, selectionof an appropriate welding hose is critical. The hose mustbe compatible with the fuel gas used to avoid hose degradationand eventual failure. SPECIFICALLY, USE GRADER & RM WITH ACETYLENE FUEL GAS ONLY. Grade Tcan be used with most fuel gases, including propane. Careshould be taken to avoid gouging, dragging, abrading orotherwise damaging the hose cover, which may also lead topremature hose failure. Do not attempt to repair or re-couplehose assemblies; replace all assemblies which show signsof age or abuse.

Thermoplastic Hose: Failure to considerhow temperature and other conditions affect hose performancecould result in death, personal injury or propertydamage. As temperature increases or decreases, burstpressure, safe working pressure, coupling retentionproperties, and other safety characteristics of the hosecan significantly decrease. The rated maximum workingpressures listed in this catalog for thermoplastic hosesare based upon a pressure test temperature of 68°F unlessstated otherwise. Deterioration due to wear, impulse,and other environmental conditions should also beconsidered. The user, through its own analysis and testing,is solely responsible for making the final selection ofthe hose and assuring that all performance, endurance,maintenance, safety and warning requirements of the applicationare met.HOSESafety & Technical DataWARNING ! Grade R & RM for use with acetylene gasONLY. Do not use with any other fuel gases. Grade Tfor use with most fuel gases, including propane. Bleedhoses when not in use for 30 minutes or longer. Couplewith one inch ferrules only.Steam Hose: The potential danger from steam in industrialhose applications is due to the great heat and pressuresinvolved. Water changes to steam at higher temperatureswhen under pressure. The greater the pressure the higherthe temperature required. If the steam escapes, tremendousquantities of heat are released. This, combined with highpressure, provides the potential danger to operators. Useonly hose specifically recommended for steam service.(Refer to RMA publication IP-11-1 "Steam Hose, Guide forMaintenance, Testing and Inspection).WARNING ! Water changes to hot water and phasesof steam when subjected to heat and pressure. Thegreater the pressure, the higher temperature required toachieve, maintain a steam phase. If the steam escapes,dangerous quantities of heat are released very suddenly.Use only steam hoses designed for the application.Parker Hannifin CorporationIndustrial Hose Productswww.safehose.com201
