Hydrant Key for 5800 and 5900 Series

This cast iron hydrant key operates ground and post hydrants in the 5800 and 5900 series. The yellow finish aids visibility on site. It meets ASME A 112.21.3M standard. Plumbers and maintenance crews use it for valve access.

Sustained Use Behaviour

The cast iron construction resists deformation during repeated valve operations. The key engages the hydrant mechanism directly without slipping. No moving parts or lubrication points require servicing. Performance stays consistent across multiple uses.

Pre-Purchase Checks

Confirm the hydrant model is a 5800 or 5900 series ground or post type. Verify the operating nut matches the key profile. Ensure local code accepts ASME A 112.21.3M compliance. No additional tools are needed for operation.
