The FT033 Tapered Pipe Insert is used to provide a tapered, smooth fit when mounting the sensor onto a 33.7mm pipe, preventing O-ring wear and damage. Without the tapered pipe insert there may be moderate resistance to mounting the sensor.
The pipe insert is constructed from an insulating polymer, isolating the sensor from the mounting pipe. If grounding is required the FT035 Grounding Spring must be used.
After fitting the slotted end of the tapered pipe insert into the mast, apply two thin continuous seams of adhesive sealant around the two shallow channels. The insert can then be fully inserted, ensuring the end of the pipe mates with the insert shoulder and any excess adhesive is wiped off. For more information, view the tutorial video.
