Teleflex Lightweight high-pressure hose is specially constructed for applications requiring strength, reliability and long-term performance along with low profile and flexibility. Added to this is the wide temperature range in which these hoses operate. These advantages combine to make Teleflex hose the choice for hot oils, phosphate esters, industrial gases and chemicals and many more.
This hose is constructed of a smooth innertube of PTFE impregnated with carbon black to provide conductivity for status dissipations. The outer braids unique bunch braid design made with 300 series stainless steel.
