How should the 3-D BullsEye be installed?
Installers should apply pipe dope or Teflon tape to the threads of the 3-D BullsEye. The 3-D BullsEye should be hand tightened. If there is any evidence of oil leakage, tighten 1/4 turn with a strap wrench and re-inspect. Continue the 1/4 turn tightening method followed by inspection until leaking stops. When installed properly, the 3-D BullsEye can withstand equipment vibration.
How can I clean/replace the 3-D BullsEye?
Since the 3-D BullsEye is installed at the top of the oil level, you will need to wait for the machinery to be turned off before attempting to remove it. Some oil will need to be drained to prevent spillage. Once removed, the 3-D BullsEye can be cleaned with soap and water. Extended periods of direct sunlight can cause “film” to build up in the 3-D BullsEye, but this can typically be wiped away when cleaned.
How durable is the material used in the 3-D BullsEye?
Polyamide is extremely durable. With excellent weathering and UV resistance, it is capable of withstanding years of exposure to sun, rain, and other extreme conditions.
I’m concerned about the 3-D BullsEye breaking. What can I do to prevent this?
The 3-D BullsEye is extremely tough and will require extreme force to break. However it is not recommended for use on mobile equipment because of the increased risk of having a high-impact collision.
When should I replace my 3-D BullsEye?
Years of exposure to extreme weather or caustic chemicals will degrade the polyamide over time. Watch for fogging and crazing (small cracks appearing on the surface of the polyamide). Given enough time, the 3-D BullsEye will degrade to a point where it is difficult to see and it will need to be replaced.
