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

These couplers are a direct replacement for the standard sized coupler mounted on many models of skid steers and attachments.

The Connect-Under-Pressure design of this coupler is ideal for High Pressure applications with a pressure rating over 5000 PSI.


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.   


Flat Face couplers are designed for applications where hydraulic spillage is a concern. One of the great advantages to the Flush Face design is that the couplers are easy to keep clean which helps to prevent contaminants from entering the hydraulic system during connection and disconnection.


Couples to any standard 1/2" body Flat Face couplers on Skid Steers and other equipment. These couplers meet or exceed the ISO 16028 standard.
