Hubert Glass Oil AW68 Hydraulic Oil 5-Gallon Pail #G68-5
The Hubert Glass Oil #G68-5 is Glass Premium 5000 Hour AW 68 anti-wear hydraulic oil in a 5-gallon pail — the 68-viscosity grade for hydraulic systems whose manufacturer specifies an AW68 fluid. Hubert Glass Oil Co. blends it in Jacksonville, Texas, and the Glass Premium line is their long-life anti-wear hydraulic range: premium Group II base oils and an OEM-approved additive system built to stay in grade over long service intervals.
On the data sheet's own numbers: 70.4 cSt at 40 °C and 9.1 cSt at 100 °C, a 105 viscosity index, a 226 °C flash point, a -26 °C pour point and a 5000+ oxidation life — the source of the product's '5000 Hour' name. The additive package carries a high level of zinc-based anti-wear protection for gears and rotors, with rust, corrosion and foam inhibitors and good water tolerance.
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 68 oil is recommended
- Logging equipment — skidders, feller bunchers, harvesters, loaders — where AW 68 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.
- Severe-duty and low-temperature service. Built for long service life under severe conditions, with excellent low-temperature performance and an OEM-approved additive system.
Questions Shops Ask
Is AW68 the right oil for my lift or press?
Follow the viscosity grade your equipment manufacturer specifies — Hubert's own data sheet says to confirm the product is consistent with the OEM recommendation for the equipment's operating conditions and maintenance practices. Where an AW 68 fluid is specified, this is it: Hubert lists hydraulic lifts, scissor lifts, presses, jacks, forklifts and lifts among the applications.
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 68, 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.
AW68 versus AW32 — which one do I need?
Viscosity: AW 68 is the heavier grade at 70.4 cSt at 40 °C against AW 32's 32.5 cSt. AW 68 suits high-pressure, high-heat systems; AW 32 flows easier in cold weather. Do not substitute one for the other unless your equipment documentation allows it — we stock both (G32-5 is the AW32 pail).
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 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. AW68 should not be substituted for AW32, AW46 or another grade unless the equipment documentation allows it. Store the pail 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.
