TL38 1/2" NPT Thread Ag Quick Connect Hydraulic Coupler Ball style 1/2" body size for Tractor Bobcat Skid Steer Loaders Implements


Q: Can the these couplers be connected with one hand and be disconnected with just pulling hyd hose out with one hand?

A: The TL38 couplers are designed for two hand  operation, although we do have another model  that will work with one hand. Please take a look at our model TL39 breakaway couplers which are designed to be mounted in a bracket that holds the collar stationary, this allows the couplers to engage or disengage with one hand operation.

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

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.
