Every CO2 supplier we could find in the Pittsburgh area (Pennsylvania) was checked one by one, and 15 of them made the list. 5 will refill the cylinder you walk in with. 5 only swap it for a different tank, which matters if yours is new or an odd size. 5 would not confirm either way, so those are marked call to confirm rather than guessed at. 7 confirm food grade CO2 for anything you actually drink; the common sizes here are 20 lb (2.5 lb and 10 lb at some branches), 5 lb, 10lb; most cover soda, beverage, industrial.

Official current beverage-gas page explicitly offers same-cylinder 'Refill While You Wait' at Tarentum for 100% CO2 and also cylinder drop-off/pickup/swap at all branches. It explicitly identifies food & beverage grade CO2 and lists the supported high-pressure CO2 cylinder sizes. Current official branch page verifies address, phone and hours. No reliable current public email was found; the official site uses a contact form. Coordinates are supported by a current local business profile.

Confirmed by West Penn Laco in October 2026: beverage grade CO2 is available in every cylinder size they carry, including the 55 lb size that restaurants and bars use. They also stock industrial 55 lb cylinders that are not beverage grade, so say what the gas is for when you order and you will be given the right one. Branches typically swap 5 lb and 20 lb cylinders and sometimes carry 2.5 lb and 10 lb, so ring ahead if you need one of the less common sizes. This is their fill plant, and the company confirmed it is the location that can fill a customer's own cylinder rather than only swapping it. Worth the trip if your cylinder is new, engraved or an odd size.
Official Butler Gas service notice explicitly states that the New Brighton store fills CO2 with a compressor and fills small customer-owned cylinders on site; the current official contact page confirms this location remains open to the public and gives current hours and phone. The published CO2 service notice dates to 2021, so exact present-day portable CO2 size limits and food-grade status are not inferred. Email is Butler Gas's current official general customer-service address. Additional evidence: https://www.butlergas.com/contact/
Official current store material explicitly advertises CO2 gas fills for paintball, soda machines, fish tanks and more. Official current contact information verifies address, phone, email and general hours. Exact CO2 cylinder sizes and food-grade status were not published.
Official current site verifies the field, address, phone, email and open-game hours and states CO2 is available on site. A current paintball field directory specifically identifies on-site CO2/Air Refills at this exact facility. Exact CO2 cylinder sizes and food-grade status were not established.

Official current beverage-gas page explicitly states cylinder drop-off/pickup/swap is available at all Greco branches, identifies food & beverage grade CO2, and lists the supported high-pressure beverage CO2 cylinder sizes. Official current Butler branch page verifies address, phone and hours. Same-cylinder refill is explicitly limited to Tarentum, so Butler is classified exchange. No reliable current public email was found; the official site uses a contact form. Additional evidence: https://www.grecogas.com/locations/butler

Official current branch page verifies this Pittsburgh-area Baden branch, address, phone and hours and explicitly lists Beverage Gases, Industrial Gases and Specialty Gases among branch services. Arc3's current location directory publishes the branch-specific email, and current company materials identify CO2 as a beverage gas product. Public evidence does not distinguish portable cylinder refill from exchange at Baden or explicitly establish branch-specific food-grade CO2 or supported sizes.
Official current site verifies the business, address, phone and email and explicitly lists CO2 in 5 lb, 10 lb, 20 lb and 50 lb containers for its beer and beverage customers. Because the site does not say whether these are customer-cylinder refills or exchanges, service_type and accepts_customer_tanks remain unknown and the published container sizes are not copied into tank_sizes under the strict refill/exchange size rule. Current directory evidence supplies regular hours.
Official current contact page verifies this open-to-public Pittsburgh headquarters, phone, hours and general customer-service email. Current Butler Gas materials confirm that the company manufactures and distributes carbon dioxide and cylinder gases, including beverage-grade CO2, but the public current evidence does not explicitly tie a portable CO2 refill versus exchange workflow or food-grade stock to this exact branch. Moat fields therefore remain conservative.
Official current contact page verifies this open-to-public Penn Hills store, phone, hours and general customer-service email. Current Butler Gas materials confirm companywide carbon dioxide cylinder and beverage-gas capabilities, but current branch-specific public evidence does not distinguish portable CO2 refill from exchange or explicitly establish food-grade stock and sizes at Penn Hills. Those moat fields remain unknown.
Official current Dale Oxygen site identifies a newly opened Pittsburgh retail gas location at 145 Delta Dr and lists Carbon Dioxide among its food and beverage gases. The official location page contains a truncated ZIP, so the correct 15238 ZIP is independently supported by current address sources. Portable customer-cylinder refill versus exchange behavior, branch-specific food-grade designation, exact sizes and a reliable public email were not established.
