Midwest Fasteners Zinc Plated Steel Inverted Flare Tube Plug

Midwest Fasteners Zinc Plated Steel Inverted Flare Tube Plug

The Midwest Fasteners Zinc Plated Steel Inverted Flare Tube Plug is a steel general fitting built to cap off and seal the end of inverted flare tube connections. Machined from steel and finished in zinc plating for corrosion resistance, this plug delivers a durable, leak-resistant seal wherever a tubing run needs to be closed off rather than joined to another line. The family is available in O.D. inverted flare sizes of 1/4", 3/16", 3/8", and 5/16", giving maintenance techs and fabricators a matched plug for nearly any standard inverted flare connection they need to shut off quickly and reliably. Each size is sold individually and held to the same O.D. flare standard across the family.

Key Features
