1/2″ NPT ISO 7241-A Hydraulic Quick Disconnect Coupler Set | Heavy-Duty Poppet Valve | Steel | Zinc Plated | Dust Caps Included | Fits Bobcat, John Deere, CAT, Kubota, CASE, New Holland | Model TL78

TL78 1/2" ISO 7241-A HEAVY-DUTY COUPLER SET – A professional-grade, industrial-strength hydraulic solution built to withstand the punishing demands of agricultural, construction, and heavy-duty machinery. These are not light-duty couplers; they are engineered for superior structural integrity and high-pressure reliability.UNIVERSAL ISO 7241-A COMPATIBILITY: Designed to meet or exceed ISO 7241-A industry standards. This set provides a perfect, factory-quality fit for 1/2" hydraulic systems on major equipment brands, including John Deere, Bobcat, CAT, Kubota, CASE, New Holland, and more.HEAVY-DUTY INDUSTRIAL ARCHITECTURE: Rated for over 4,410 PSI, these couplers are forged from high-strength steel and finished with a premium trivalent zinc plating. This rugged construction ensures maximum protection against rust, oxidation, and the extreme mechanical stresses of daily, high-intensity field work.FIELD-READY ERGONOMICS: Featuring a push-connect locking sleeve with heavy knurled texturing, the TL78 allows for a secure, non-slip grip—even when working in mud or while wearing heavy protective gloves.TOTAL SYSTEM PROTECTION: The set includes high-quality protective dust caps. By sealing the hydraulic interfaces when not in use, you prevent dirt, moisture, and environmental contaminants from entering your system, which is critical for extending the service life of your pumps and control valves.Specifications Details Specification Model Number TL78 Coupler Body Size 1/2" Coupler Thread Size 1/2" NPT Coupler Material Type Heavy-Duty Steel Plating Type Corrosion-resistant trivalent zinc Package Includes (1) Male Coupler, (1) Female Coupler, (2) Protective Dust Caps Frequently Asked QuestionsQ: Why choose the TL78 for my agricultural tractor? A: The TL78 is specifically optimized for tractors, seeders, trailers, and sprayers. Its heavy-duty poppet valve design ensures consistent fluid flow and reliability in the diverse, harsh conditions found in the agricultural sector, where equipment failure during the harvest or planting season is not an option.Q: Is this set compatible with my skid steer? A: Yes. Because it adheres to the universal ISO 7241-A standard, the TL78 is highly versatile and compatible with the hydraulic circuits on many skid steer models from brands like Bobcat, CAT, and others that utilize this standard series.Q: How does the "no air inclusion" feature help my hydraulic system? A: During disconnection, standard couplers can allow air into the hydraulic lines, which causes "spongy" performance and can lead to cavitation in high-pressure pumps. The precision engineering of the TL78 ensures a clean break, minimizing air inclusion to maintain the responsiveness and health of your hydraulic circuit.
