TL71 3/8" NPT Thread Hydraulic Coupler Set ISO 7241-B 3/8 body Poppet Bobcat Skid Steer Coupling with Dust Caps

These couplers are a direct replacement for the standard sized coupler mounted on many models of skid steers and attachments. ISO 7241-B is one of the most used coupling design worldwide, These are NOT light duty couplers. The sturdy design of heavy duty TopLine couplers have become well known for their durability and ability to withstand rugged conditions. Our coupler sizes fit many models of: Bobcat, John Deere, CAT, Kubota, New Holland, CASE, JCB, Thomas, Gehl, Volvo, and ASV skid steers. Couples to any standard 1/4" body ISO 7241-B couplers on Skid Steers and other equipment. These couplers meet or exceed the ISO 7241-B standard. - Heavy Duty design. Rated at over 3600 PSI - Couples to any standard 3/8” ISO 7241-B coupler - Push-connect locking sleeve design - Exceeds ISO 7241-B standards - Corrosion-resistant zinc plating - No air inclusion during disconnection - Heavy knurled sleeves for non-slip grip - Includes dust caps to protect from the elements INTERCHANGES WITH: ISO 7241 Series Aeroquip FD45 Series Dixon H Series Faster HNV Series Parker 60 Series Safeway S-10 Series Snap-Tite 72 Series Stucchi IRB Series TL71 3/8" BODY ISO 7241-B HYDRAULIC COUPLER SET (3/8" NPT THREAD) – The TL71 is an industrial-grade, heavy-duty hydraulic coupler set engineered for maximum reliability in demanding environments. Built to the ISO 7241-B standard, this set is designed to survive high-pressure spikes and harsh site conditions, making it an ideal choice for skid steers and agricultural implements that require a secure, long-lasting connection.ADVANCED SEALING TECHNOLOGY: Unlike standard couplers, the TL71 features a PTFE (Teflon) back-up ring which prevents "seal washout"—a common failure where high-pressure fluid forces the seal out of its groove. Additionally, the captive valve seal ensures the poppet remains tightly seated, providing a superior leak-proof barrier when disconnected.HEAVY-DUTY INDUSTRIAL RATING: Rated for over 3600 PSI, this coupler is constructed from high-strength steel. It is built to withstand the continuous stress of professional heavy-machinery operation, ensuring that your auxiliary lines remain leak-free under load.ISO 7241-B COMPLIANCE: Meeting or exceeding international ISO 7241-B standards, these couplers provide guaranteed interchangeability with existing 3/8" poppet-style hydraulic systems across major brands like Bobcat, John Deere, CAT, and more.FIELD-READY ERGONOMICS: The heavy knurled locking sleeve is designed for maximum grip, allowing operators to connect or disconnect lines easily, even with muddy hands or while wearing heavy safety gloves. SpecificationsModel Number TL71 Coupler Body Size 3/8" Coupler Thread Size 3/8" NPT Thread Inner Diameter 0.63" Thread Dash Number -06 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: What is "seal washout," and how does the PTFE back-up ring stop it? A: Seal washout occurs when high-pressure hydraulic fluid forces the rubber seal out of its internal housing, causing the coupler to leak internally or externally. The PTFE back-up ring acts as a rigid support that prevents the rubber seal from extruding under pressure, significantly increasing the coupler's lifespan in high-pressure systems.Q: Why is a "captive valve seal" important? A: In many standard couplers, the seal around the poppet (the valve that stops the oil) can drift or deform, leading to slow leaks. A captive seal is physically locked into the design, ensuring that every time the poppet snaps shut, it creates a perfect, consistent seal every single time.Q: Are these suitable for high-vibration environments like demolition? A: Yes. Because they are designed with heavy-duty construction and high-grade materials, they are built to handle the intense, constant vibrations of demolition attachments, where lighter-duty couplers would likely rattle loose or experience internal seal failure.Q: Can I use these on my tractor? A: The TL71 is compatible with any hydraulic system using the ISO 7241-B standard. It is commonly found on compact tractors, skid steers, and agricultural implements. Just ensure your machine’s ports utilize the 3/8" body size.
