J.w. Winco 743.1-24-M33X1.5-A Oil Level Sight Glass

Product Description

The J.W. WINCO 743.1-24-M33X1.5-A is an aluminum oil level sight glass designed for visual monitoring of fluid levels in industrial machinery, gearboxes, and lubrication systems. It features an M33x1.5 thread for secure installation into threaded ports and a 36mm distance across flats for standard wrench engagement. The flange diameter measures 40mm, and the head height is 8.5mm, making it suitable for installations where low-profile fittings are required. This component is installed by millwrights, maintenance technicians, and industrial mechanics performing routine equipment servicing or upgrades.

This sight glass is commonly used in industrial and manufacturing environments where oil level monitoring is required on gearboxes, hydraulic reservoirs, pumps, and other fluid-containing equipment. The M33x1.5 thread pitch and aluminum construction make it appropriate for moderate-pressure, non-corrosive fluid applications. Technicians typically install it during scheduled maintenance intervals or when replacing damaged or fouled sight glasses in existing equipment.

Key Features

• Aluminum construction for lightweight, corrosion-resistant service in standard lubrication applications
• M33x1.5 thread provides a secure, leak-resistant fit in compatible threaded ports
• 36mm distance across flats allows engagement with standard metric wrenches
• 40mm flange diameter provides a positive seating surface against the equipment housing
• Low-profile 8.5mm head height suits installations with limited clearance

Compatibility

Designed as an OEM-style replacement or upgrade sight glass for industrial machinery and equipment with M33x1.5 threaded oil-level ports requiring a 36mm across-flats fitting.

Installation Notes

Installation should be performed by a qualified maintenance technician or millwright. Shut down and de-energize all related machinery and relieve system pressure before removing or installing any sight glass fitting. Use an appropriate metric wrench on the flats - do not use pipe wrenches or pliers on the flange. Thread sealant selection should be compatible with the system fluid type and the aluminum fitting material.
