Hubert Glass Oil AW32 Hydraulic Oil 55-Gallon Drum #G32-D
The Hubert Glass Oil #G32-D is Glass Premium 5000 Hour AW 32 anti-wear hydraulic oil in a 55-gallon drum — the lighter of the two Glass Premium grades Alamo stocks, for hydraulic systems whose manufacturer specifies an AW32 fluid. Hubert Glass Oil Co. blends it in Jacksonville, Texas, on the same premium Group II base oils and zinc anti-wear additive system as the rest of the Glass Premium line.
On the data sheet's own numbers: 31.9 cSt at 40 °C and 5.4 cSt at 100 °C, a 100 viscosity index, a 220 °C flash point, a -26 °C pour point and a 5000+ oxidation life. The thinner grade means faster cold-weather flow and easier cold starts on equipment spec'd for AW 32 — the common choice where the manufacturer calls for a light hydraulic fluid rather than a heavy one.
Where It Works — Per the Data Sheet
- Hydraulic systems operating under high pressure and high heat
- Farm tractors with separate, add-on hydraulic tanks (buckets, bale spikes)
- Construction equipment — front-end loaders, excavators — where AW 32 oil is recommended
- Logging equipment — skidders, feller bunchers, harvesters, loaders — where AW 32 oil is recommended
- Hydraulic lifts in muffler shops, scissor lifts, trash compactors
- Dump trucks, hydraulic jacks, log splitters, car haulers, lift gates, hydraulic presses, forklifts
Features & Benefits
- Zinc anti-wear protection. A high level of zinc anti-wear additives for maximum protection to gears and rotors.
- Rust, corrosion and foam control. Inhibits rust, corrosion and foaming, and aids in water tolerance.
- Long service life. Premium Group II base oils with outstanding resistance to high-temperature oxidation and thermal stability — 5000+ oxidation life.
- Cold-weather service. The lighter 32-grade flows easier at low temperatures, with excellent low-temperature service and an OEM-approved additive system.
Questions Shops Ask
AW32 versus AW68 — which one does my equipment need?
Viscosity: AW 32 runs 31.9 cSt at 40 °C against AW 68's 70.4 cSt. The thinner AW 32 flows easier in cold weather and is the grade where the manufacturer calls for a light hydraulic fluid; AW 68 is the heavier grade for high-pressure, high-heat systems. Never substitute one for the other unless the equipment documentation allows it — we stock both grades in pails and drums (G68-D is the AW68 drum).
What does '5000 Hour' mean?
It is Hubert's oxidation-life rating for the Glass Premium line — the data sheet lists an oxidation life of 5000+ for AW 32, which is where the product name comes from. The right drain interval for your equipment still depends on the OEM's guidance and your operating conditions.
Is AW32 the same as ISO VG 32 hydraulic oil?
Yes — 'AW 32' is the anti-wear hydraulic designation for the ISO VG 32 viscosity grade, and Hubert's SDS lists the Glass AW line by ISO grades (32, 46 and 68). The data sheet's 31.9 cSt at 40 °C sits squarely in the 32-grade band.
Is it safe to handle and ship?
Per the Safety Data Sheet (SDS 9706, Rev 6, dated 2025-12-30), this oil is not classified as hazardous under 29 CFR 1910.1200 (2012), is not regulated as dangerous goods for DOT transport, and carries NFPA/HMIS ratings of Health 0 / Flammability 1 / Reactivity 0. Two cautions from the sheet matter in a shop: a high-pressure injection under the skin needs immediate medical attention, and leaks near ignition sources are a fire hazard. Used oil goes to a collection service, not the trash.
Why Buy from Alamo
- We stock the consumables your equipment actually runs on. Hydraulic oil in the grades shops call for, by the drum or the pail — one order, no scavenger hunt.
- We help match the grade before the order ships. AW32, AW46, AW68 — tell us what the equipment spec says and we confirm it.
- Questions on fit, quantities or scheduling a fill? Call (817) 865-3707.
Fitment & Setup
Always confirm the viscosity grade your equipment manufacturer specifies before filling. AW32 should not be substituted for AW46, AW68 or another grade unless the equipment documentation allows it. Store the drum sealed and out of ignition sources, and route used oil to a collection service. Need help matching a fluid or part to your equipment? Call Alamo Equipment at (817) 865-3707.
