Lovelysp 2PCS G3/4" air compressor oil sight glass aluminum alloy hexagonal sight tool sight glass oil tank gauge male thread for pump air compressor parts

Product Name: G3/4" Air Compressor Oil Sight GlassProduct material: Aluminum alloyProduct color: SilverProduct dimensions: Sight glass diameter 33mm/1.29inch, inner diameter 21mm/0.82inch, height 18mm/0.71inchProduct application: Air compressor oil is mainly used for oil level observation in industrial compressors, refrigeration units, air compressors and some hydraulic systems. Direct visual inspection through a transparent window or monitoring of lubricating oil volume with the aid of an oil level dipstick is an important monitoring component for preventing equipment from running out of oil and ensuring the normal operation of the lubrication system. It is widely used in daily maintenance and inspection.Product usage method: The oil sight glass of the air compressor is installed vertically or horizontally on the designated G3/4 inch interface of the compressor oil tank or oil trough, and is fixed by tightening it with threads. When installing, sealant or gaskets should be used to ensure the sealing of the interface. On a daily basis, the oil level can be directly observed through the transparent window to see if it is within the marked range, and a quick check can be completed without disassembly.Product application scope: The boring sight is suitable for various reciprocating and screw compressors and refrigeration units with G3/4-inch pipe threads at the interface. It is commonly found in factory gas source systems, refrigeration units in cold storage, construction machinery and other equipment. The working pressure is usually applicable to medium and low pressure lubrication systems. The specific pressure needs to be matched with the design pressure of the equipment and the temperature of the medium.Product content: 2pcs* sight toolsNoteKeep the parts out of reach of children.For manual measurement, please allow for minor dimensional errors of the items.Due to different screen displays, the actual color may vary slightly.

• High-strength aluminum alloy material: The main body of the boring sight is formed by die-casting high-quality aluminum alloy, featuring high structural strength and lightweight characteristics. It has excellent pressure resistance, can stably withstand the internal pressure fluctuations of the compressor system, and effectively resist external impacts, ensuring no deformation or cracking during long-term use, and significantly extending its service life.
• Precise oil level dipstick design: The sight tool window often features lines or colored marking areas, clearly indicating the normal, minimum, and maximum oil level ranges. The marking is wear-resistant and does not fall off, enabling maintenance personnel to quickly and accurately determine the oil level status, facilitating timely replenishment or control of the oil level, and optimizing the efficiency of equipment maintenance.
• High-transparency and wear-resistant window glass: The sight adopts a tempered glass transparent window with a light transmittance of over 90%, allowing the oil level to be clearly visible. It has a high surface hardness, is scratch-resistant, and is not prone to fogging or aging when in long-term contact with oil agents, ensuring a long-lasting and clear field of vision and reducing the risk of misjudgment.
• Wide-temperature environmental adaptability: The overall design of the flip-type sight takes into account the characteristics of thermal expansion and contraction, maintaining structural stability within the range from the low-temperature condition of the compressor's cold start to the full-load operation at high temperatures. The junction between glass and metal adopts a flexible seal to prevent cracking or leakage caused by temperature difference stress.
• Oil-resistant and temperature-resistant sealing system: The sealing ring on the oil tank surface is made of fluororubber, which has excellent compatibility with compressor lubricating oil. It can maintain elasticity within the temperature range of -30℃ to 150℃, prevent oil leakage, and ensure the long-term reliable sealing of the observation mirror in high-temperature and high-pressure environments.
