Locke Supply Co. in Oklahoma City: A wholesale plumbing distributor for contractors and homeowners
Locke Supply Co. is a plumbing supply distributor in Oklahoma City that stocks pipe, fittings, fixtures, and tools for both licensed plumbers and DIY customers. The company operates as a cash-and-carry wholesaler, meaning customers select and purchase inventory directly rather than ordering through a contractor account, and it carries brands commonly specified in residential and light commercial work across central Oklahoma.
What Locke Supply Co. actually does
Locke Supply stocks plumbing materials at wholesale pricing without requiring a contractor license or business tax number to shop. The distributor functions as a middle ground between big-box retailers (which sell at retail markup) and specialized contractor-only suppliers (which require licensed accounts). This positioning makes it useful for plumbers restocking on the job, homeowners tackling repairs or renovation, and handymen who are not licensed plumbers but need reliable parts and pricing better than Home Depot or Lowe's.
The business carries copper and PVC pipe in standard sizes, brass and PVC fittings, supply stops, rough-in valves, water heaters, and hand tools. Inventory leans toward residential jobs: you will find what you need for a toilet repair, a water line replacement, or a bathroom rough-in, but the stock is not as deep as a distributor serving commercial mechanical contractors.
Services, inventory, and pricing
Locke Supply operates on a cash-and-carry model. Customers walk in, locate items from shelves, and pay at the counter. There is no ordering delay, no minimum purchase, and no contractor account setup required. This works well for plumbers who forgot a fitting on a job site or homeowners who need a part same day.
Pricing is wholesale rather than retail. A copper elbow that costs $3 to $5 at a big-box store might cost $1.50 to $2.50 at Locke, depending on size and current market rates for copper. (Copper prices fluctuate; confirm current pricing before a large purchase.) PVC fittings and schedule 40 pipe are similarly discounted relative to retail. Water heater pricing is typically 10 to 20 percent below box-store prices for the same tank size and efficiency rating.
The company does not offer delivery, installation, or custom fabrication. It does not accept special orders for slow-moving or discontinued items. If Locke does not stock it on the shelf, you will need to source it elsewhere or place a special order through a contractor supply house.
How Locke Supply compares to other Oklahoma City plumbing suppliers
Locke Supply differs from three main categories of competitors in Oklahoma City.
Box retailers (Home Depot, Lowe's, Ace Hardware): These operate at retail markup, so a basic copper fitting costs 50 to 100 percent more than at Locke. Inventory depth is wider for common residential items, but you pay for breadth. Most useful when you need one or two items and want to avoid a second trip.
Contractor-only distributors (such as Watsco or local HVAC + plumbing supply houses): These require a business license, resale certificate, or contractor license to open an account. Pricing is lower than Locke's on high-volume orders, but you cannot walk in and buy one fitting. Suited to licensed plumbers who do repeat work and want net-30 terms.
Independent local plumbing shops (smaller family-run supply counters): Oklahoma City has several. Pricing is often equivalent to Locke, but inventory may be smaller and hours less convenient. These are worth calling if Locke is out of stock on a specialty item.
Choose Locke if you need wholesale pricing without paperwork, want to walk in same day, and are buying residential supplies. Choose a contractor distributor if you are licensed and do enough volume to justify an account. Choose a box retailer if you need 20 different items for a kitchen remodel and want one-stop shopping.
Who Locke Supply suits
Locke is most useful for plumbers who stock supplies on their work vehicles and need to top up without ordering, homeowners doing their own repairs or minor renovations, and handymen who are not licensed plumbers. It suits someone who knows what they want (has a part number or size in mind) and is ready to pick it up immediately.
Locke does not suit someone who needs delivery, design advice, or a contractor to install the parts. It is not the place to call at 2 a.m. for an emergency repair; it is not open then, and it does not offer emergency service. It also does not suit large commercial projects where a job-site account with delivery and net terms is essential.
What a first visit involves
Walk in during business hours, locate the section for your type of job (water lines, drain/vent, rough-in, etc.). Most locations have the shelves organized by material type and size. Grab what you need, go to the counter with your part list or sketch, and ask a staff member if you cannot find something. Pay by cash or card, take your receipt, and leave. The entire trip is typically 10 to 20 minutes for a small to medium order.
If you are unsure of a part size, bring a sample or measurements. Staff can help match you to the right fitting, but the focus is on speed and stock, not design consultation.
Hours, location, and logistics
Locke Supply operates Monday through Friday, 7 a.m. to 5 p.m., and Saturday 8 a.m. to noon. (Verify hours before a weekend trip, as holiday schedules may shift.) The store is located in northwest Oklahoma City with street parking and a small lot. There is no online ordering or curbside pickup; you must enter the building and shop in person.
Locke Supply fills the gap between retail markup and contractor-account friction in Oklahoma City's plumbing market. It is the fastest way to get wholesale pricing on standard residential supplies if you know what you need and can pick it up the same day.
