Luneta 3D Sight Glass 3/4 inch BSPP

High-Definition View

Compared to other bullseye sight glasses, the Luneta Sight Glass provides a crystal-clear, undistorted view of in-service oils. You'll notice the difference immediately . This level of clarity is achieved by our manufacturing process and the use of Tritan, which allows for much thinner outer walls than acrylic sight glasses.

Heavy-Duty Durability

The Luneta Sight Glass is 4x stronger than traditional acrylic sight glasses, shatterproof and chemically resistant. In fact, it's made with a proprietary copolyester that is stronger than bulletproof glass. The Luneta Sight Glass can take a beating and withstand harsh environments, including extreme temperatures.

• Durable
• One-piece, high-impact Tritan construction makes it the toughest site glass available
• Resistant to chemical wear and buildup
• Integrated threads means no leaking between sightglass and machine port
• Convenient
• The Sight Glass extends from the machine, providing a clear view of oil
• Molded-in hex nut means a quick, simple installation
