TL40-MF 1/2″ NPT Flat Face Connect Under Pressure Hydraulic Quick Couple Set

Have you ever had trouble connecting attachments to your skid steer on a hot day? This is actually a common problem, especially in the summertime. What happens is the oil in the lines expands from the heat and creates pressure. This male end flat face coupler is designed to connect with pressure still in the lines. An added plus to the Flat Face design is that these couplers are easy to keep clean which helps to avoid contaminants entering the hydraulic system. These couplers meet or exceed the ISO 16028 standard so you can be sure that they will couple to the standard couplers used on most skid steers and other hydraulic equipment. These are very heavy duty couplers that are designed to stand up to the most demanding jobs. With a pressure rating of over 5000psi, you can be sure that they are up to the task. We are also including a dust cap with this coupler to help keep your hydraulic system clean. Some of the design features of this coupler are: - Locking sleeve design to prevent accidental disconnection - Heavy knurled sleeve for non-slip grip. - Corrosion-resistant plating Flat mating surface easy to clean. - No air inclusion during disconnection 1/2” NPT female thread Couples to any standard 1/2" body size Flat Face coupler - Exceeds the ISO 16028 standard (Rated at over 5000PSI). TL40-MF 1/2" BODY FLAT FACE CONNECT-UNDER-PRESSURE HYDRAULIC COUPLER SET (1/2" NPT)The TL40-MF is a heavy-duty flat-face hydraulic coupler set designed for skid steers, loaders, attachments, and other compatible equipment. Built for applications using the ISO 16028 flat-face coupler standard, these couplers provide a reliable hydraulic connection for demanding equipment applications involving brands such as Bobcat, John Deere, CAT, Kubota, New Holland, CASE, JCB, Thomas, Gehl, Volvo, ASV, and others. Always verify coupler specifications and compatibility before ordering.CONNECT-UNDER-PRESSURE CAPABILITY: Designed for applications where residual hydraulic pressure may remain trapped in a disconnected line. The connect-under-pressure design can help make attachment changes easier when pressure remains in the hydraulic circuit due to conditions such as heat expansion. Always follow proper hydraulic safety procedures and the equipment manufacturer's recommendations.HEAVY-DUTY INDUSTRIAL RATING: Rated for over 5076 PSI and constructed from high-strength steel, the TL40-MF is designed for demanding hydraulic applications involving high operating pressures, frequent equipment use, and challenging work environments.SPILL-RESISTANT FLAT-FACE DESIGN: The flush-face profile is designed to help minimize hydraulic fluid loss during disconnection and makes the coupling surfaces easier to clean. Keeping couplers clean and protected helps reduce the entry of dirt and debris into the hydraulic system during connection and disconnection.PRECISION LOCKING MECHANISM: The push-connect locking sleeve features heavy knurled texturing for an improved grip during connection and disconnection. The textured sleeve helps make attachment changes easier, including when the operator is wearing protective work gloves.CORROSION-RESISTANT FINISH: Trivalent zinc plating provides added protection against moisture and environmental exposure, helping protect the couplers from corrosion during demanding outdoor applications.SPECIFICATIONSModel Number: TL40-MF Coupler Body Size: 1/2" Coupler Thread Size: 1/2" NPT Thread Inner Diameter: 0.77" Thread Dash Number: -08 Coupler Material: Heavy-Duty Steel Plating Type: Corrosion-Resistant Trivalent Zinc Package Includes: 1 Female Coupler, 1 Male Coupler, 2 Protective Dust CapsFREQUENTLY ASKED QUESTIONSQ: Are these Flat Face or Ball Style couplers?A: These are Flat Face couplers designed for applications using the ISO 16028 standard. The flat, flush mating surface helps minimize fluid loss during disconnection and makes the coupling surfaces easier to clean compared with traditional AG-style couplers. Always verify that your equipment requires the ISO 16028 Flat Face style before ordering.Q: Why is the Connect-Under-Pressure feature important?A: Hydraulic attachments can sometimes retain residual pressure after being disconnected, particularly when pressure increases due to heat expansion. A connect-under-pressure coupler is designed to help connect hydraulic lines when residual pressure is present, making attachment changes easier in certain field conditions. Follow proper safety procedures and never attempt to connect couplers under pressure beyond the coupler's rated capability.Q: Are these compatible with my machine?A: The TL40-MF is designed for compatible 1/2" body Flat Face hydraulic coupler applications using the ISO 16028 standard. It may be suitable for replacement or connection applications involving equipment from manufacturers such as Bobcat, John Deere, CAT, Kubota, New Holland, CASE, JCB, Thomas, Gehl, Volvo, and ASV. Always verify the coupler body size, connection style, thread size, pressure rating, and specifications required by your specific machine or attachment before ordering.Q: How do I identify if my machine uses AG-Style or Flat Face couplers?A: Inspect the coupler face. If the mating surface is flat and flush, it is typically a Flat Face coupler, such as an ISO 16028 style. If the coupler has a visible valve mechanism with a spring-loaded button or ball-like center, it is typically an AG-style poppet or ball-detent coupler. The two styles are not interchangeable, so you must match the coupler style, body size, thread type, and specifications required by your equipment.
