Midwest Hearth Gas Fire Pit Key Valve Kit — 3/4" NPT, 1/2" NPSM Floor Plate Flat Black, Solid Brass 1/4-Turn Control

The Midwest Hearth Gas Fire Pit Key Valve Kit is a solid-brass, 3/4" NPT ball valve assembly with a flat-black floor plate and 8" key designed to give durable, low-resistance on/off control for natural gas or propane fire features.

This kit combines a heavy-duty brass ball valve, a 1/2" NPSM floor-plate flange, and a matching flat-black key to create a tidy, reliable access point for a gas fireplace, gas log set, or outdoor fire pit. It’s built for straightforward installation and frequent use, with a 1/4-turn ball valve that minimizes pressure loss and resists wear. The package is CSA certified to industry ANSI Z21.5/CSA standards and supports both natural gas and LPG/propane systems.

How does this kit make operating a gas fire pit easier?

The 1/4-turn ball valve gives immediate open or closed control with minimal effort and no noticeable pressure drop, so you can light or extinguish your flame quickly. The included key and floor plate create a neat, accessible point for regular use while protecting connections below the surface.

• Solid brass valve for long-term reliability and corrosion resistance
• Ball-valve design preserves gas pressure while providing tight shutoff
• 8" flat-black key gives leverage for effortless operation
• Floor plate offers a finished look and protects the valve opening

What are the installation and safety highlights I should know?

Installers must start with the main gas supply closed and clear any debris from the supply line before attaching the valve. Use gas-rated Teflon tape on threaded joints, avoid over-torquing the valve, and perform a low-pressure leak test with soapy water per the included guidance.

• Screw valve onto threaded supply pipe in CLOSED position
• Blow out grit and use gas-rated thread sealant on all joints
• Run a 2 PSI pressure test and apply soap/water to detect leaks
• Do not use excessive torque when tightening the valve

Which systems and appliances is the valve compatible with?

The kit is designed to serve a wide range of gas appliances both indoors and outdoors. It works with natural gas and liquid propane systems and suits fireplaces, gas log sets, log lighters, and fire pits where a durable manual shutoff and access key are required.
