Parker KP80042 Hydraulic Hose Cap 0.375 in 9200 Psi Steel

Product Description

The PARKER KP80042 is a steel hydraulic hose cap designed to seal and protect the open end of a hydraulic hose during storage, transport, or system downtime. Part of the Parker FNL Series with Seal-Lok geometry, it fits hoses with a 0.375-inch outside diameter and carries a maximum working pressure rating of 9,200 psi. The cap measures 0.74 inches in overall length and meets SAE 52011-2 standards. It is installed by hydraulic system technicians, maintenance mechanics, and fluid power specialists on industrial and mobile hydraulic circuits where port or hose-end contamination control is required.

This cap is suited for use on 3/8-inch hydraulic hose ends in both industrial and mobile equipment applications. The Seal-Lok style interface provides a reliable seal at the hose termination point, preventing fluid loss and keeping contaminants out of open lines during service intervals or extended equipment storage. It is commonly used on construction equipment, agricultural machinery, and industrial power units where hydraulic line integrity must be maintained between service calls.
