Two - Window Oil Sight Glass (BSP Copper) for Gas Stations
These two - window oil sight glasses, crafted from pure copper, are specifically designed for gas stations. They serve a crucial function in the dispenser pipeline system, allowing operators to visually inspect the oil for purity and the absence of air bubbles.
Key Features
Material and Durability: The sight glasses are made of pure copper, which undergoes anti - oxidation electroplating. This treatment significantly extends their service life, ensuring long - term reliability in the harsh environment of a gas station.
Sealing and Resistance: A nitrile rubber ring is incorporated into the design. This ring offers excellent oil resistance and low - temperature resistance, effectively preventing oil leakage and maintaining the integrity of the oil flow system.
Movable Joint Design: Available in 3/4" and 1" high - hanging types, these sight glasses are equipped with all - copper movable joints. The movable joints are surface - electroplated, and internally sealed with an oil - resistant leather ring. This design allows for flexible rotation and is highly durable.
Thread Types and Installation
There are two types of installation threads for users to choose from:
BSP Straight Thread: It comes with an O - ring and uses the sealing ring for effective sealing.
NPT Tapered Thread: This type does not have a sealing groove and requires the use of pipe filler or sealant for sealing.
Additional Design Details
The oil sight gauges feature 2 windows with large viewing areas, which are commonly used for easy observation. The outer diameter of the installation thread is approximately 26mm, while the outer diameter of the installation hose fine thread joint is around 24mm. The flow apertures are 19mm and 17mm, ensuring proper oil flow through the sight glass.
