Hex Socket Plug 18x1.5mm Stainless Steel

The Hex Socket Plug 18x1.5mm Stainless Steel from DAYTONA SENSORS is a precision oxygen sensor plug designed for automotive exhaust systems and sensor applications requiring reliable sealing. This plug serves as a threaded closure for oxygen sensor ports, exhaust bungs, and similar ports found in aftermarket exhaust systems, engine testing equipment, and performance tuning installations.

Manufactured from stainless steel for superior corrosion resistance and heat tolerance, this plug features an 18mm x 1.5mm male thread specification that matches standard oxygen sensor port dimensions across most automotive applications. The hex socket head design allows installation and removal using standard metric hex wrenches.

Professional mechanics, exhaust system builders, and engine tuners benefit most from stocking this plug for permanent or temporary sensor port closure during diagnostic work, custom exhaust installation, or emissions testing.
