What Types of Transformer Oil Do We Buy?
We purchase all major dielectric fluid types used in power and distribution transformers. Whether you're holding mineral oil from a cancelled project, natural ester fluid drained during a retrofill, or synthetic ester stock that no longer fits your maintenance program, we are active buyers. Oil does not need to be in perfect condition — we evaluate every submission on its own merits.
Mineral Transformer Oil
We buy Type I uninhibited and Type II inhibited mineral insulating oil meeting ASTM D3487 specifications, including major brands such as Nytro, Voltesso, Diala, and Luminol. Both new unused stock and used in-service oil are considered.
Natural Ester Dielectric Fluid
We purchase FR3 (Cargill Envirotemp), VG-100 (Prolec GE), Midel eN 1204, Midel eN 1215, and other natural ester fluids. Natural ester is in high demand — unused or lightly used stock commands strong pricing.
Synthetic Ester Transformer Oil
We buy Midel 7131, NYTRO BIOTEC, and other synthetic ester fluids. Due to the premium cost of synthetic ester new, surplus stock holds significant resale value.
What Quantities and Packaging
Do We Accept?
There is no minimum quantity requirement. We evaluate submissions ranging from a few 55-gallon drums to full tanker loads and bulk storage tanks. Common packaging formats we purchase include 55-gallon drums, 330-gallon totes, and tanker truck quantities. If your oil is in a fixed storage tank on-site, note that in your submission and we will discuss logistics directly.

Frequently Asked Questions
Do you buy used or contaminated transformer oil?
Yes. We consider used, reclaimed, and off-specification oil in addition to new unused surplus. Condition affects pricing but does not disqualify a submission. PCB status must be disclosed — we do not purchase oil with known PCB content exceeding regulatory thresholds
How do you determine the offer price?
Offers are based on oil type, brand, condition rating, quantity, packaging format, location, and current market pricing for that fluid category. Natural ester and synthetic ester fluids generally command significantly higher prices than mineral oil due to their cost new. Providing a Certificate of Analysis and oil sample photo helps us return the strongest possible offer.
How long does it take to receive an offer?
We respond to all submissions within one business day. Complex or large-volume inquiries may require a sample for our lab to test or additional documentation before we provide a proposal.
Do I need to have the oil tested before submitting?
No. Test results are helpful and will strengthen your offer, but they are not required to submit. If you have a Certificate of Analysis on hand, upload it with your submission. If not, we may request one before finalizing an offer on larger quantities.
What geographic areas do you serve?
We purchase transformer oil located anywhere in the continental United States. Alaska and Hawaii are not currently served.
Why Sell Your Surplus Oil Through TransformerParts.com?
Most utilities, contractors, and industrial facilities have no established channel for selling surplus dielectric fluid. Oil sits in storage, occupying space and depreciating, while the owner has no clear path to liquidate it. TransformerParts.com operates as an active buyer in the transformer oil secondary market — we know what this oil is worth, we have buyers, and we move quickly. Submitting takes less than five minutes. An offer follows within one business day.
