Description: 1/4" , 3/8" & 1/2" 'Poppet style Agricultural Hydraulic Couplers

These quality couplers come in 3 body size/threads sizes. Please check measurements in photos to ensure size compatibility if mixing with your existing couplers. These are the most common 'poppet' style coupler used on agricultural equipment (1/2" are by far the most common size).

These couplers have BSP threaded female ends, they are the ideal choice where a tough, durable product of Superior Quality is required.

A poppet valve is used to minimize the pressure drop characteristics and provide a positive sealing arrangement. Please check photos/measurements to ensure fit. This Series conform to ISO 7241-1 Series A.

Keeping hydraulic oil systems clean is extremely important if you want your pumps & valves to last. Tolerances are measured in thousands of a MM, so a piece of grit or dirt introduced via a dirty poppet can end up resulting in catastrophic failure.

To help eliminate contaminants, we advise always using plugs & caps when the Poppets are disconnected. Please select this option from 'drop box' next to price. Also if you would like more than 1 pair, insert desired amount into 'quantity ' box.

Typical applications include: Earthmoving equipment, construction, manufacturing, chemical processing, agricultural equipment and general industrial machinery.

The above price is for one pair, (one set which includes one male and one female coupler)
