Abstract: A fluid level measuring device, also referred to as a dipstick, for measuring the fluid level in a fluid reservoir or tank, such as an oil pan or transmission reservoir in an internal combustion engine. The fluid level measuring device includes a stationary tube assembly in which a dipstick assembly is disposed. The dipstick assembly includes a fluid level indicator measuring blade attached to an elongated shaft which is directly molded into a plastic handle assembly. The plastic handle assembly includes a bayonet type locking mechanism for locking the handle to the stationary tube assembly. A compressible seal forms a pressurized seal between the stationary tube assembly and the handle.
