These adaptors are common on petroleum tank trailers (crude, gasoline, diesel) for bottom loading and unloading. The kit replaces a cracked, clouded, or leaking sight glass, so the operator can visually monitor fuel flow and maintain a leak‑free seal. If your sight glass is damaged or weeping fuel, this kit restores the adaptor to safe, working condition.
