Parker Hannifin’s Lubrication Hoses are specifically designed for grease and lubrication, making it easy to properly perform quick and effective preventive maintenance on all types of equipment. These hoses are compact and eliminate gallons of unnecessary ‘in-line’ grease versus larger bore rubber hoses. In addition, they are a light weight and highly flexible alternative to traditional rubber hoses. Parflex HLB hose operates in temperatures from –40°F up to +212°F. For extreme temperatures (–100°F up to +450°F) Parflex 919 PTFE hose can be outfitted with the same style bulkhead grease zerk fitting as the HLB hose. The wide temperature range of PTFE hose makes it ideal for operating in extreme temperatures below -40°F and above 212°F as in cold climates or hot environments for example in applications on paving equipment where rubber hose will bake and crack.
