Elesa+Ganter HCFE.20-3/4 Oil Level Sight Glass Technical Guide
The Elesa+Ganter HCFE.20-3/4 oil level sight glass is a widely useful component for industrial tanks and housings where fast visual oil inspection matters. In systems that depend on proper lubrication or stable hydraulic fluid levels, a simple viewing element can make maintenance routines more efficient and more reliable.
This model belongs to the standard HCFE series and is designed for installations using a G 3/4 threaded oil level sight glass. It offers a practical combination of visibility, material durability, and compact integration, making it relevant in both new equipment design and replacement maintenance work.
Technical Features of HCFE.20-3/4
The HCFE.20-3/4 uses a G 3/4 thread and is manufactured from transparent polyamide-based technopolymer (PA-T). It includes an NBR synthetic rubber flat washer for sealing and is rated for a maximum continuous working temperature of 100°C. The listed dimensions are A 10.5 mm, B 19.5 mm, D 31.5 mm, d 25 mm, and s 27 mm. The recommended tightening torque is 6 to 8 Nm.
Why This Oil Sight Glass Is a Practical Choice
An effective oil level sight glass allows technicians to confirm oil level without opening the reservoir. That may sound simple, but in a real production environment it can save time, reduce contamination risk, and support faster maintenance checks.
The HCFE.20-3/4 is especially useful where service teams want a dependable hydraulic oil level indicator that remains easy to read and easy to install. The transparent window helps users track whether the fluid level remains within the intended range during daily or scheduled inspections.
Elesa+Ganter HCFE.20-3/4 Typical Application Areas
This model is suitable for hydraulic power packs, gearbox housings, industrial lubrication units, oil tanks, and machinery reservoirs. Because it uses a G 3/4 connection, it is particularly relevant in equipment designed around BSP threaded interfaces.
It can also serve as a replacement part where an existing industrial oil sight glass needs to match established thread and dimensional constraints. That helps maintain specification consistency without overcomplicating maintenance planning.
Installation and Care
Correct tightening is important to achieve sealing without damaging the washer or overstressing the component. The technopolymer body should not be exposed to alcohol or alcohol-based detergents. Where reservoir wall thickness is below 5 mm, a GH brass nut is available on request for improved fitting support.

Elesa+Ganter HCFE.20-3/4 FAQ
What is the main function of the Elesa+Ganter HCFE.20-3/4 oil level sight glass?
Its function is to provide direct visual monitoring of oil or lubricant level inside a machine reservoir or housing. This makes routine inspection faster and supports preventive maintenance without unnecessary system opening.
Elesa+Ganter HCFE.20-3/4 What thread size does HCFE.20-3/4 use?
This model uses a G 3/4 thread. That makes it suitable for industrial systems and reservoirs built around BSP-style thread specifications of the same size.
Is the HCFE.20-3/4 suitable for hydraulic applications?
Yes, it is suitable for many hydraulic and lubrication-related applications, provided the operating conditions and fluid compatibility are aligned with the published material specifications.
What material is used for the sight glass body?
The body is made from transparent polyamide-based technopolymer, chosen to provide visibility while maintaining practical durability for industrial use.
Why does tightening torque matter for this component?
Using the recommended torque helps maintain proper sealing and keeps the sealing washer correctly positioned. This reduces the risk of leaks and supports stable long-term performance in service.
