Frequently asked questions

At GID Industrial (Elite.Parts' parent company), we specialize in procuring industrial parts. We know where to find the rare and obsolete equipment that our customers need in order to get back to business. There are other companies who claim to do what we do, but we're confident that our commitment to quality and value is unparalleled in our field.

Warranties differ by part and by which suppliers we use to procure it for you. Sometimes, a part will be sold as-is and without a warranty. Our specialty, single board computers, tend to receive a one-year warranty.

Elite.Parts can ship via FedEx, UPS, DHL, and USPS. We have accounts with each of them and generally ship using one of those, but we can also ship using your account if you would prefer. However, we can use other carriers if it will be more convenient for you.

Absolutely! We are happy to serve customers regardless of location. We work with international clients all the time, and we are familiar with shipping to destinations all across the globe.

All major credit cards are accepted: Visa, MasterCard, Discover, and American Express. We will also accept payment made with wire transfer or PayPal. Checks will only be accepted from customers in the USA. Terms may available for larger orders, upon approval.

HARD TO FIND A BETTER PROVIDER

Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

Applied Materials

CONSISTENTLY DELIVERS QUALITY SOLUTIONS

Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE

This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

Trican Well Service

GO TO SOURCE

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
