These couplers are the professional standard for ensuring reliable fluid transfer between tractors and their implements, providing the structural integrity required to withstand demanding field conditions.RUGGED CONSTRUCTION: These are not light-duty connectors. Built from heavy-duty steel and rated for pressures exceeding 3600 PSI, the TL37 is engineered to survive the constant vibrations, pressure spikes, and harsh environmental challenges of professional farming and construction operations.ISO 5675 PRECISION: Meeting or exceeding ISO 5675 standards, these couplers ensure compatibility with Ag-style (poppet) ports found on a wide array of tractor brands, including John Deere, Kubota, New Holland, CASE, and more. This makes them an ideal choice for replacing worn-out factory components on implements and machinery.POPPET VALVE EFFICIENCY: The classic poppet valve design is engineered to minimize fluid loss and prevent air inclusion during disconnection. This helps maintain consistent hydraulic performance and protects your pump and motor from premature cavitation and wear.FIELD-READY ERGONOMICS: Designed for quick, efficient service, the push-connect locking sleeve features heavy knurled texturing. This provides a secure, non-slip grip, allowing you to connect or disconnect your attachments in seconds, even while working in the field with thick safety gloves.Specifications Model Number TL37 Coupler Body Size 1/2" Coupler Thread Size 1/2" NPT Thread Inner Diameter 0.77" Thread Dash Number -08 Coupler Material Type Heavy-Duty Steel Plating Type Corrosion-resistant trivalent zinc Package Includes (1) Male Ag-Style Coupler, (1) Female Ag-Style Coupler, (2) Protective Dust Caps Frequently Asked QuestionsQ: Are these compatible with my tractor's hydraulic ports?A: Yes. The TL37 follows the industry-standard ISO 5675 Ag-style (poppet) configuration. They are designed as a heavy-duty replacement for many 1/2" body Ag-style ports on tractors from manufacturers like John Deere, CAT, Kubota, and many others.Q: How is the poppet design different from Flat Face couplers?A: Unlike Flat Face couplers, which have a flush surface, Ag-style couplers use a poppet valve that sits inside the coupler. The poppet design is a long-standing industry standard known for reliable performance and ease of use in agricultural settings.Q: What is the benefit of the trivalent zinc plating?A: Agricultural and construction equipment is frequently exposed to moisture, mud, and corrosive materials. Trivalent zinc plating provides a protective barrier that helps shield the base steel from oxidation and rust, helping the couplers function reliably for years of operation.Q: Is it necessary to use the included dust caps?A: Yes. Keeping the hydraulic interface clean is essential for maintaining reliable hydraulic system performance. The included dust caps help shield the coupler opening from dirt, debris, and moisture when the hydraulic lines are disconnected.
