Aqualine QCK-100 Brass Quick Coupler Key 1 in Mipt 3/4 in Fipt

Product Description

The AQUALINE QCK-100 is a brass quick coupler key designed to open and operate quick coupler valves in irrigation systems. It connects to a 1-inch male iron pipe thread (MIPT) inlet and offers a 3/4-inch female iron pipe thread (FIPT) outlet, giving the installer flexibility in hose or riser connections at the valve access point. Brass construction provides corrosion resistance and long service life in direct-burial and above-grade irrigation applications. This key is a standard tool for irrigation technicians and landscape contractors performing routine system maintenance or connecting portable water supply equipment to in-ground quick coupler stations.

The QCK-100 is suited for residential and light commercial landscape irrigation systems where quick coupler valves are installed along the main supply line. It is inserted into a quick coupler valve body to unlock and allow water flow, then removed after use. The 1-inch MIPT connection threads into compatible quick coupler valve sockets, while the 3/4-inch FIPT outlet accepts standard hose-thread adapters or risers for attaching sprinkler heads or hose assemblies.

Key Features

• Brass body for corrosion resistance in outdoor and buried irrigation environments
• 1-inch MIPT inlet fits standard quick coupler valve sockets
• 3/4-inch FIPT outlet accepts common hose adapters and risers
• Compact key design for fast insertion and removal during irrigation service

Compatibility

Designed as an OEM-style replacement and service key for brass quick coupler valves with 1-inch valve sockets commonly found in residential and commercial landscape irrigation mainlines.

Installation Notes

Installation and service of quick coupler valves and keys should be performed by a licensed irrigation technician or qualified plumber in accordance with local plumbing and irrigation codes. Shut off the irrigation system main supply and relieve line pressure before inserting or removing the coupler key. Inspect the valve socket for debris before insertion to avoid thread damage to the brass key. Do not use pipe wrenches or excessive torque on the key body.
