Parker KP17587 Steel Flared Tube Plug 1-1/4 in 37 Degree

Product Description

The PARKER KP17587 is a steel flared tube plug designed to seal 1-1/4 inch OD tubing with a 37-degree flare end connection. It provides a pressure-rated termination point in hydraulic, pneumatic, or fluid-transfer lines where a port or tube end must be blanked off cleanly and securely. Rated to 4000 psi maximum working pressure and up to 500 degrees F, this plug handles demanding industrial and mobile hydraulic service. Overall length is 1.45 inches and weight is 0.97 pounds. Installation is handled by hydraulic technicians and pipefitters working on high-pressure fluid systems.

This plug is suited for use in industrial machinery, mobile equipment, and fluid power systems where a 37-degree SAE flare connection must be capped or temporarily closed. It is appropriate for applications operating at or below 4000 psi and 500 degrees F. The flare-end design ensures a metal-to-metal seal consistent with SAE J514 and ISO 8434-2 standards. Sold individually, it is a direct-fit component for new installations and field repairs requiring a reliable tube-end closure.

Compatibility

Designed for use with 1-1/4 inch OD tubing fitted with a 37-degree flare end connection, consistent with SAE J514 and ISO 8434-2 flare fitting systems.

Installation Notes

Installation is typically performed by qualified hydraulic technicians or pipefitters. Depressurize and isolate the hydraulic or fluid system completely before removing any existing fittings or installing this plug. Ensure mating flare surfaces are clean and free of damage before assembly to maintain a proper metal-to-metal seal. Follow SAE J514 assembly guidelines for thread engagement and flare seating.
