Machined in the USA to ASA, ASME, and SAE standards, the brass ferrule compresses onto the tube OD to create a leak-free mechanical joint that holds up under vibration and repeated thermal cycling.\u003c\/p\u003e\n\n\u003ch2\u003eSigns You Need a New Compression Sleeve\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eAir or fluid leaking at a compression fitting joint\u003c\/li\u003e\n  \u003cli\u003eFitting will not hold torque or the tube pulls out under pressure\u003c\/li\u003e\n  \u003cli\u003eVisible cracks, flared lips, or corrosion on the existing sleeve\u003c\/li\u003e\n  \u003cli\u003eJoint was disassembled — compression sleeves should not be reused\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eMidland Industries\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e18003\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003ePart Type\u003c\/th\u003e\n\u003ctd\u003eCompression Sleeve (Ferrule)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eTube Size\u003c\/th\u003e\n\u003ctd\u003e1\/4\" OD\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eBrass\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eCompatible Tubing\u003c\/th\u003e\n\u003ctd\u003eCopper, Aluminum, Thermoplastic (not steel)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eOperating Pressure\u003c\/th\u003e\n\u003ctd\u003eUp to 1200 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eTemperature Range\u003c\/th\u003e\n\u003ctd\u003e-65°F to +250°F\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eStandards\u003c\/th\u003e\n\u003ctd\u003eASA \/ ASME \/ SAE\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth scope=\"row\"\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eCross References\u003c\/h2\u003e\n\u003cp\u003eThis part replaces or is equivalent to the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMidland:\u003c\/strong\u003e 18-003\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cp\u003eUsed in 1\/4\" compression fittings on non-steel tubing for:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAir brake lines and auxiliary pneumatic circuits\u003c\/li\u003e\n  \u003cli\u003eFuel supply and return lines (copper or nylon tubing)\u003c\/li\u003e\n  \u003cli\u003eDEF lines and other low-pressure fluid transfer\u003c\/li\u003e\n  \u003cli\u003eInstrumentation, marine, and industrial hydraulic fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003ePair with a matching 1\/4\" compression fitting body and nut.
