Q: What makes the TL21 Hydraulic Quick Connect Coupler a superior choice?
A: The TL21 is built for high-performance use with a heavy-duty steel body and a robust pressure rating of over 5,000 PSI. It is specifically engineered to withstand tough, high-flow (up to 23 GPM) environments while delivering consistent, leak-free performance.
Q: How does the flat face design improve performance?
A: The flat face design significantly reduces fluid loss during connection and disconnection while minimizing the introduction of contaminants. This enhances hydraulic system longevity and reduces equipment downtime due to maintenance.
Q: Is the TL21 compatible with my skid steer or equipment?
A: Yes. The TL21 is compatible with many skid steers and attachments from major brands including Bobcat, John Deere, CAT, Kubota, CASE, JCB, and more. Its standard 1/2" body size ensures broad compatibility across various hydraulic systems.
Q: Does the product include any protective accessories?
A: Yes, the TL21 set includes protective dust caps for both the male and female couplers. These caps help prevent dirt, debris, and moisture from entering the hydraulic system when the couplers are disconnected.
Q: Can the TL21 be used as a direct replacement?
A: Absolutely. The TL21 is designed as a direct replacement for many standard flat-face hydraulic couplers used on skid steers and other hydraulic machinery. Its standardized sizing makes for a simple, straightforward installation.
