Description

If you’ve been crawling under your tractor to check hydraulic oil levels with a dipstick or just guessing whether you’ve got enough fluid, it’s time to put those days behind you. This replacement sight glass puts your hydraulic oil monitoring right at eye level where a quick glance tells you everything you need to know about fluid level and condition. When your hydraulic system is working hard running loaders, implements, and three-point hitches, keeping proper fluid levels isn’t just maintenance—it’s protecting thousands of dollars worth of pumps and valves.

What You’re Getting

Clear tempered glass window that won’t yellow or crack under pressure cycles
Heavy-duty housing built to handle high hydraulic pressures without leaking
Chemical-resistant construction that stands up to all types of hydraulic fluids
Direct replacement design that installs exactly like the original
Sealed mounting that prevents contamination and maintains system integrity

Built for Real Farm Work

These tractors—from the versatile T6 series handling loader work and field cultivation to the powerful TM series pulling heavy implements and the utility-focused TSA models running multiple hydraulics—depend on clean, properly filled hydraulic systems. Whether you’re operating a T6.155 with a front loader all day at the dairy or running a TM175 with complex implements that demand full hydraulic flow, this sight glass helps you catch low fluid levels before air enters the system and causes expensive pump damage.

Made to Last

Quality sight glasses use tempered glass that maintains clarity through years of temperature swings and chemical exposure. The robust housing withstands system pressures and vibration while the sealed design keeps dirt and moisture out of your hydraulic oil. You’ll get reliable visual monitoring that doesn’t cloud up or crack when you need it most.

Good to Know

Before installation, make sure hydraulic pressure is relieved and the system has cooled—hot hydraulic oil can cause serious burns. Clean the mounting area thoroughly and use new O-rings or gaskets as specified. Many operators mark minimum and maximum fluid levels on the housing with a paint marker for quick reference during daily checks. If your old sight glass was cloudy or stained, consider changing your hydraulic filters and oil since contamination leaves its mark on the glass.
