Oil Level Gauge, Oil Sight Glass, Air Compressor Fitting, 1/2 PT Male Thread Aluminum Alloy Cap with O-Ring

Thread Type: 1/2 PT (approximately 20.4mm outer diameter); Overall Dimensions: 26 x 15mm/1" x 0.6" (D*T).

MATERIAL: The main body is made of aluminum alloy, which is less prone to wear and cracking than plastic. It can operate in high-temperature environments.

GOOD SEAL: Sealing is achieved with a peripheral O-ring. The O-ring is made of high-quality rubber, resistant to high temperatures, corrosion, and oxidation. It provides excellent sealing performance.

WIDE APPLICATION: The oil level sight glass is widely used to check the oil level in the pump of an air compressor.

The actual fluid level in the oil reservoir can be checked by placing the sight glass on the reservoir to see and externally assess whether the screw oil pressure regulator is meeting operating conditions.
