Pneumatic Quick CouplingsOperationParker E-z-mate couplings combine push-to-connect,exhaust-style action with a self-locking valve sleeve to guardagainst accidental disconnection. Simply follow the directionof the On-Off arrow stamped on the yellow chromate valvesleeve. It’s that easy.To connect, push the nipple into the coupler. The black lockingsleeve automatically slides forward securely locking the nipplein place. No air is allowed to flow through the coupling at thispoint. The yellow chromate valve sleeve is then rotatedclockwise (when viewed from the coupler port end) to openflow and automatically engage the sleeve-lock mechanism.To disconnect, rotate the valve sleeve counter clockwise(when viewed from the coupler end). The flow of air throughthe coupling will be shut off and all downstream air is ventedto the atmosphere. The locking sleeve may now be retractedand the nipple removed. Lubricate sleeve as part of periodicmaintenance to coupler.SpecificationsBody Size (in.) 1/4 3/8 1/2 3/4Rated Pressure (PSI) 300 300 300 300Temperature Range (std seals) -40° to +250° F.Locking Device 4 balls 4 balls 6 balls 8 ballsForce required to Connect (lbs) Less than 10Vacuum ServiceNot recommendedHow To OrderEZ - 251 - 4 FPPort ConfigurationFP - Female PipeMP - Male PipeHB - Standard Hose BarbPL - Push-Lok Hose BarbPort Size (1/16 of an inch)Unit1 - Valved Coupler4 - Unvalved NippleBody Size25 - 1/4"37 - 3/8"50 - 1/2"75 - 3/4"E-z-mate SeriesSpecial Purpose – Exhaust - SteelE-z-mate Series Industrial InterchangeFeatures• Parker's E-z-mate is an exhaust type coupler that is designedto exhaust air pressure prior to the disconnection process.• The valve sleeve acts as an integral shut-off valve thatallows connection and disconnection at zero pressure.When the sleeve is moved to shut off air flow, itautomatically vents downstream allowing for disconnectionat zero pressure and eliminating the risk of “hose whip.”• Meets ISO 4414 requirements for a controlled pressurerelease system.• Built-in sleeve-lok mechanically locks the valve sleeve tohelp prevent accidental disconnects.• Proven ball locking mechanism evenly distributes load toresist wear and provide positive connections. The balllocking mechanism also provides accurate alignment andallows a swiveling action to reduce hose torque.• O-ring interface seal assures “bubble tight” seal and longservice life.• E-z-mate Series couplers use industrial interchange nipples.• Brass versions available.
