Elesa+Ganter 11111 HCFE.30-1.1/4 Oil Level Sight Glass

The Elesa+Ganter 11111 oil level sight glass, model HCFE.30-1.1/4, is a transparent technopolymer component used for direct oil level inspection in industrial reservoirs, hydraulic systems, gearboxes, and lubrication equipment. It provides a simple and reliable visual reference point for maintenance teams.

Technical Description

This HCFE model has a G 1 1/4 thread and a 30 mm inspection size. It is manufactured from transparent PA-T polyamide-based technopolymer, allowing operators to observe the fluid level without dismantling the system or exposing the oil to contaminants.

The component is designed for a maximum continuous working temperature of 100°C. It uses an NBR synthetic rubber sealing washer, which supports reliable sealing when the sight glass is tightened correctly. The recommended tightening torque is 8–10 Nm.

Why Visual Oil Level Monitoring Matters

Low oil level can lead to overheating, poor lubrication, pump wear, gear damage, and unplanned downtime. A sight glass helps operators identify level changes quickly during scheduled inspections. The Elesa+Ganter 11111 HCFE.30-1.1/4 oil level sight glass is particularly useful in machinery where routine visual checks are part of preventive maintenance.

Installation and Maintenance Notes

Correct mounting is important for sealing performance. The specified torque range should be followed to avoid under-tightening or excessive compression of the washer. The transparent body should not be cleaned with alcohol-based detergents. If the reservoir wall is thinner than 5 mm, a compatible brass nut accessory may be considered depending on the application.
