Message: [QUOTE="mandkole, post: 864515, member: 4630"] Im gonna disagree here with garbage mechanic here... I've currently work for and sell hose for a manufacturer of hydraulic hose and have for 30 years. As long as the hose assembly is made correctly, for your application, a 100R2 hose from a pressure perspective would almost be overkill. The HP oil supply system in a PSD is [U]not[/U] an impulsing application. The main thing I'd be concerned with your selection is the temperature rating. Id want at least 250F, but the modern CPE tube products have 300F. The old school nitrile construction 212F hoses will be marginal under exposure over time. Im not going to get into a pissing contest on what mfgrs are best as there are good hose mfgrs with good products and I know guys at all of the majors. Parker is an awesome marketer of hose. But, I have extensive background on how we [I]test/develop [/I]materials, hose and hose/coupling interface at Gates and [U]no one[/U] exceeds the benchmark performance our products. (for disclosure, I use a Megatech 3000 hose assembly on my HP oil crossover and will eventually move all of the hoses that way. This hose is catalog rated to 300F, 3K psi, but is peak and square wave impulse tested to 4K and bursts at 12K minimum.) [/QUOTE]
