Heavy-Duty Brass Fuel Flow Indicator with Four Round Holes for Dispenser
The HBSYJ-XX Series Four Round Holes Oil Indicators are engineered for installation between a fuel dispenser and the fuel hose, providing clear visual confirmation that fuel is flowing properly. Unlike typical aluminum or acrylic indicators, this series features a high-quality brass body combined with high-borosilicate glass, delivering superior durability, oxidation resistance, and long-term reliability in demanding fueling environments.
Globally, this product is known by a variety of names. In the United States, technicians often call it a Brass Inline Fuel Sight Glass or Fuel Flow Indicator. In the United Kingdom and other Commonwealth countries, it is referred to as a Petrol Flow Visual Indicator. In Germany and other European countries, it is often called a Kraftstoff-Durchflussanzeiger. In Asian markets, it may be described as a Fuel Sight Glass with Four Windows or simply a Brass Oil Indicator. Regardless of the terminology, the function remains the same: providing real-time, accurate fuel flow monitoring to ensure safe and efficient dispensing.
The robust brass construction of the HBSYJ-XX series ensures enhanced mechanical strength and resistance to wear, surpassing the performance of aluminum alternatives. The male-threaded bushing is also made of brass and features a chrome-plated surface for corrosion protection and a professional appearance. Inside, reinforced structural elements improve strength under operational pressure, ensuring reliable performance over time.
The high-borosilicate glass allows for clear visual monitoring while resisting oxidation and chemical degradation, making it ideal for long-term use in fuel dispensing systems. This four-window design provides multiple sight points, ensuring operators can quickly and confidently verify fuel flow without additional instruments.
The HBSYJ-XX series is compatible with standard fuel hoses according to HG-T 3037. Specific sizes include 3/4-inch male BSPP or NPT thread suitable for 3/4-inch hose with 19 mm inner diameter and 30 mm outer diameter, 3/4-inch male BSPP or NPT thread suitable for 1-inch hose with 25 mm inner diameter and 37 mm outer diameter, 1-inch male BSPP or NPT thread for 3/4-inch hose (19x30 mm), and 1-inch male BSPP or NPT thread for 1-inch hose (25x37 mm). This flexibility ensures compatibility with a wide range of fuel dispensing setups.
Key benefits of the HBSYJ-XX series include its four-window visual design for precise monitoring, durable brass construction, high-borosilicate glass resistant to oxidation, and flexible thread compatibility. These indicators enable operators to maintain high safety standards, reduce the risk of improper fuel flow, and enhance overall efficiency at fueling stations, LPG dispensers, and industrial fuel systems.
The HBSYJ-XX Series Brass Oil Flow Indicators are the optimal choice for those seeking robust, long-lasting, and visually reliable fuel flow verification, suitable for commercial, industrial, and export-oriented fueling systems worldwide.
