3D BullsEye View Port

3D BullsEye View Ports In comparison to standard windows, the 3D BullsEye occupies these following advantages:

  • Machined from one solid piece of impact-resistant, high strength, stain-resistant cast acrylic.

  • Acrylic material can withstand temperatures as low as -40°F (-17°C) and as high as 230°F (110°C) at atmospheric pressure.

  • Round polished end designed for easier and more accurate viewing from any angle, making the job of a maintenance inspector painless.

  • Under normal operating conditions, the view port does not have a limited life span.

  • Excellent resistance to hydrocarbon and petroleum-based products, hydraulic fluids, most silicone fluids and fuels.

  • NPT sizes are available in: 1/4”, 1/2”, 3/4”, 1”, 1 1/4”, 1 1/2” and 2” (inches).
    		• 3D Oil Window
    Avoid Teflon Tape

    BullsEye Installation For installation of the 3D BullsEye, installers should:

  • Apply “pipe dope” to the threads of the view port. Note: Avoid using any products containing Teflon, including Teflon tape.

  • Hand tighten the view port first, and then turned 1/4 turn with a chain wrench, belt wrench or arc joint pliers.

  • If there is any evidence of oil leakage, tighten 1/4 turn and re-inspect. Continue the 1/4 turn, followed by inspection, until there is no oil leakage.


    • Simply the best, most efficient oil level viewing port, period.
