Submit your equipment details through our Request a Quote form. You can enter your part number, specifications, or upload a photo of your machine's nameplate or dimensional drawing. Our engineering desk will verify exact OEM fitment and return pricing. Standard components are quoted same-day; engineered configurations within 24 hours.

We understand that downtime costs you money, so we process orders immediately. Most standard in-stock components ship within 1 to 2 business days from our US-based warehouse network. If you are in a severe break-fix scenario and require emergency air freight or hot-shot delivery, please call our urgent support line at (833) 833-0586 (Monday–Saturday, 7 AM to 7 PM) or submit a Quote Request marked as "Machine Down" for immediate technical triage.

We serve both the United States and Canada. To ensure rapid delivery, our inventory dispatches from our US or Canada-based fulfillment centers and partner facilities. For our Canadian buyers, our streamlined cross-border logistics guarantee zero border delays or surprise customs friction.

If you catch the mistake quickly and notify us before the component has physically left our warehouse or OEM partner facility, we will cancel the order for a 100% full refund. However, once a part is loaded onto a carrier's truck and is in transit, the order cannot be cancelled. It will be treated as a standard return, subject to applicable restocking fees and freight charges.

While standard parcels will receive a typical tracking link, the majority of our heavy process components ship via commercial Less-Than-Truckload (LTL) freight. Once your pallet is dispatched, we will email you a carrier-specific PRO Number. You will use this PRO Number directly on the freight carrier's website (e.g., XPO, Old Dominion, YRC) to track your pallet's route to your loading dock.

Deliveries are dock-to-dock or curbside only. The freight driver will not move the pallet inside your facility. Your facility must have a loading dock or a forklift readily available to safely unload the heavy freight from the back of the semi-truck.

Freight damage is rare, but you must protect your facility by inspecting the pallet before signing the driver's delivery receipt (Bill of Lading). If there is major visible damage, write "DAMAGED" on the paperwork, refuse the shipment, and contact us immediately. If you sign for the freight as "Clear" and discover hidden damage later, you have a strict 5-business-day window to report it to us so we can file a carrier claim on your behalf.

If your shipment arrives and appears to be missing an item or accessory, you must report the shortage to us at orders@gconparts.com within 3 business days of delivery. Claims for missing parts made outside of this window cannot be verified and will be denied.

We know parts can sometimes sit on a receiving dock for a few days, so you have 30 days from delivery to request a return. Because we sell severe-duty equipment, returned parts must be in brand-new, uninstalled, and resellable condition. Installed parts (showing bolt marks, grease, or thread wear) cannot be returned.

Yes. Forensically inspecting and repackaging heavy industrial parts requires significant manual labor and forklift time. To cover these intake costs, standard stock components are subject to a 15% restocking fee, and specialized concrete/process components are subject to a 25% restocking fee. Custom-built or special-order items are non-returnable.

Note: If a return is required because we made a shipping error, we waive all fees and cover the return freight.

While our team is happy to provide expert technical guidance and manufacturer spec sheets, it is ultimately the buyer's responsibility to verify compatibility, flange patterns, and pneumatic requirements for their specific plant prior to ordering. If you are unsure, do not guess. Upload a photo of your nameplate or submit your equipment specs through our Request a Quote form, and our technical desk will verify exact OEM fitment before you buy.

To ensure rapid processing and immediate dispatch of your first order, we require payment in advance via major credit card or wire transfer. Because formal credit checks take several days to process, this ensures your urgent parts ship without delay. Once a successful initial trading history is established, you may apply for corporate Net 30 terms. Established accounts can email their formal Purchase Orders to orders@gconparts.com.

Yes. We are an authorized distributor for top-tier industrial brands. All components are sold with the full backing of the original equipment manufacturer's (OEM) warranty.

While the physical part itself is covered under the OEM warranty, Griffin Construction Parts (a division of GRIFFIN GROUP Inc.) does not assume financial liability for consequential damages, including lost revenue, lost profits, or plant downtime resulting from a delayed delivery or component failure. Our maximum liability is limited strictly to the replacement or refund of the purchased component.
