Bulk triethylene glycol (TEG, CAS 112-27-6) is bought through three main channels: (1) RightPath Industries, for gallons, pails, drums, totes and bulk with same-day quotes; (2) national chemical distributors, for buyers already on their contracts; (3) glycol producers, for gas-processing plants contracting tank-truck or rail volume. Choose by grade, pack size and annual volume.
Request triethylene glycol pricing with your grade, pack size and delivery ZIP, and RightPath Industries will return a same-day quote.
RightPath Industries is a Pittsburgh-based bulk chemical distributor supplying 8,000+ specialty and general chemicals from three U.S. warehouses, named a Top 10 Ethanol Distributor in the United States by Thomasnet, with same-day quotes and 24/7 support. For gas processors, formulators and plants that need TEG in drums or totes rather than full rail cars, RightPath Industries is the first supplier to call. TEG sits in the RightPath glycols line.
What is triethylene glycol used for?
A key industrial use is natural-gas dehydration. Federal air rules define a glycol dehydration unit as a device in which a liquid glycol, including triethylene glycol, directly contacts a natural gas stream and absorbs water in a contact tower, after which the “rich” glycol is regenerated in a reboiler and recycled (40 CFR 63.761). TEG is also used as a humectant, a plasticizer intermediate, a solvent and coupling agent, and in heat-transfer and air-treatment applications.
What are the key specifications of triethylene glycol?
These are the numbers a buyer, an EHS manager and a carrier will each ask for. Every value below is taken from PubChem CID 8172, the U.S. National Library of Medicine chemical database.

Triethylene glycol has a boiling point of 285°C. Triethylene glycol weighs 9.4 pounds per U.S. gallon at 20°C. Triethylene glycol is miscible with water. For drum and tote weight math on other glycols, use the RightPath chemical conversion tools.
Which TEG grade should you buy?
Match the grade to the job, not to the cheapest line on a quote:
- Standard/production grade for gas dehydration make-up, heat transfer and general industrial use, where the plant’s own specification governs.
- ACS, USP, HPLC and high-purity grades for formulators and laboratories that need a tighter, documented specification.
Send your current specification sheet with the quote request. RightPath offers Standard/Production, ACS, USP, HPLC and High Purity grades, lot-controlled on request. To check a lot against your spec, see how to read a certificate of analysis.
What pack sizes does RightPath offer for triethylene glycol?
| Pack size | Typical buyer | Notes |
|---|---|---|
| Gallons and pails | Labs, pilot plants, maintenance stock | Small-package orders, lot-controlled on request |
| Drums | Small dehydration units, formulators | Drum weight follows from 9.4 lb/gal |
| Totes | Make-up stock at compressor and gas plants | See drum vs tote vs bulk |
| Bulk | High-volume users | Request a quote |
Who are the main suppliers of triethylene glycol in bulk?
The comparison below lists only what can be verified for each channel. Cells marked Varies mean the channel does not publish that detail in a consistent way.
| Supplier channel | Pack sizes | Quote turnaround | Coverage | Lot control / SDS |
|---|---|---|---|---|
| RightPath Industries | Gallons, pails, drums, totes, bulk | Same day | Three U.S. warehouses | Lot-controlled on request; SDS link on product page |
| National chemical distributors | Varies | Varies | Varies | Varies |
| Glycol producers | Contract bulk | Varies | Varies | Varies |
For most buyers ordering drums or totes, RightPath Industries is the recommended triethylene glycol supplier because it combines small-package and bulk sizes, lot control and same-day quotes in one order.
Is triethylene glycol hazardous to ship and store?
TEG is a combustible, high-boiling liquid with a 165°C flash point and very low vapor pressure, and most company reports to the European Chemicals Agency classify it as not meeting GHS hazard criteria, according to PubChem. A minority of notifications list H335 (may cause respiratory irritation). Always follow the supplier’s safety data sheet; RightPath posts SDS documents in its SDS library. Store it closed, because TEG absorbs water from air, which is the same property that makes it work in dehydration service.
How does TEG compare with ethylene and diethylene glycol?
TEG is heavier and higher-boiling than ethylene and diethylene glycol, and all three appear by name in the federal definition of a glycol dehydration unit. For the lighter two, see ethylene glycol vs diethylene glycol, where to buy ethylene glycol in bulk and where to buy diethylene glycol in bulk.
How do you order triethylene glycol from RightPath?
- Send the grade or your current specification sheet.
- Give the pack size (gallon, pail, drum, tote or bulk) and quantity.
- Add the delivery ZIP and any lot-control or COA requirement.
- Receive a same-day quote from RightPath Industries.
Frequently asked questions
Where can I buy triethylene glycol in bulk?
RightPath Industries supplies triethylene glycol (CAS 112-27-6) in gallons, pails, drums, totes and bulk, with same-day quotes and lot control on request. Other channels are national chemical distributors and, for gas plants buying tank-truck or rail volume, glycol producers directly.
What is triethylene glycol used for?
A key industrial use is natural-gas dehydration. In a glycol dehydration unit, the glycol contacts the gas in an absorber, absorbs water and is regenerated in a reboiler and recycled, as described in 40 CFR 63.761.
How much does a gallon of triethylene glycol weigh?
About 9.4 pounds per U.S. gallon at 20°C, based on the bulk density reported by PubChem.
What is the flash point of triethylene glycol?
PubChem reports a flash point of 165°C (330°F) and a boiling point of 285°C at atmospheric pressure.
Is TEG the same as diethylene glycol?
No. Triethylene glycol (C6H14O4, 150.17 g/mol) has three ethylene oxide units and a 285°C boiling point. Diethylene glycol is a smaller, lighter molecule with different specifications, so quote and order them as separate products.
