DEL product warranty

Our warranty

We stand behind every part we make. If a DEL product fails because of a defect in materials or workmanship, we cover it for 1 year in service or 18 months from the date of original sale from DEL, whichever comes first.

The warranty covers the part itself, and only against defects in materials and workmanship. It does not cover the labor to remove or install it. It does not cover misuse, improper installation, or damage, whether accidental or intentional. A proper install follows industry practice for air controls: clean, dry, filtered and regulated air.

DEL inspects every return and decides the final outcome: credit, repair, replacement or denial. We do our best to honor the outcome you asked for, but an RA number does not guarantee a specific outcome.

Sending a part back

Start with a return request online, or give us a call. Photos of the label, the valve and how it is installed help us the most. We review every request and email you a Return Authorization (RA) number. Please don't ship anything until you have it.

The RA email comes with a sheet to print. Put it in the box with the parts, and tape the tag at the bottom to the outside of the box, next to your carrier's label. When the parts arrive, we inspect them and let you know what we found.

Returning a part that isn't under warranty

We take back unused parts within 30 days of shipping. Depending on condition, we may charge a restock fee of up to 25% of the price paid. That includes parts that need cleaning, repackaging or repair before we can sell them again.

After 30 days, call us first. We look at those case by case and set the fee then. The same goes for custom consoles, top plates and other special builds.

There is no restock fee on warranty claims, or when the mistake was ours, like a wrong part shipped.

You pay the freight to send parts to us. We pay to ship warranty repairs and replacements back to you, and we pay both ways when the mistake was ours.

Please ship within 30 days of getting your RA number. After that it can expire, and you will need to request a new one.

Credit goes to your account after we inspect the parts, less any restock fee. It covers the part only, not freight or other charges. If a part doesn't pass inspection, we can send it back at your cost or scrap it, whichever you prefer.

If your return doesn't fit these terms, call us anyway. We can make exceptions.
