Parker KP80043 Hydraulic Hose Cap 0.5in 9200psi Seal-lok

Product Description

The PARKER KP80043 is a steel hydraulic hose cap designed to seal and protect the open end of a 0.5-inch OD (1/2-inch nominal, 8 mm hose size) hydraulic hose fitting. Built to a maximum working pressure of 9,200 psi, this cap is part of the FNL Series and uses a Seal-Lok interface for a leak-free, positive seal. At 0.87 inches in overall length and weighing just 0.01 pounds, it is a compact protective component used to cap off hose assemblies during storage, transport, or whenever a hydraulic circuit must be isolated. Installation and removal are handled by hydraulic technicians and maintenance mechanics working on mobile or industrial hydraulic systems.

This cap is suited for use in high-pressure hydraulic systems where contamination control and pressure retention are critical. It is applied when capping unused hose ends on mobile equipment, industrial machinery, or hydraulic test benches. The Seal-Lok face-seal design eliminates thread-dependent sealing and minimizes the risk of leaks even under pressure cycling. Sold in packages of 4, it is a practical stocking item for shops that frequently assemble or service hydraulic hose assemblies.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Always depressurize and bleed down the hydraulic system before removing or installing any fitting cap. Inspect the Seal-Lok face-seal surface for nicks or contamination before seating the cap. Follow applicable equipment manufacturer torque specifications and SAE guidelines for Seal-Lok fittings when tightening.
