Thread Locked Type Hydraulic couplings

1. Machined from solid steel barstock for durability.2. The QKTL Series employs a threaded sleeve locking mechanism,mates with matching male threads on the nipple.The two halves must be manually threaded together for connection.3. Hard,chrome alloy balls are used for valving. They a spring loaded for positive seating of the valve.4. The valve provides a metal-to-metal seal between the ball and a coined seat.5. The body seal is polyurethane which resists high pressure extrusion.6. A threaded valve retainer provides a valves stop that assures positive valve alignment.

QKTL Series couplings with their threaded union locking system and precision ball-type check valves are designed for extreme high pressure applications such as found on portable hydraulic rams.See pages noted in Table of Contents for dust plugs and caps for the Parker full line of hydraulic couplings
