1) Can I buy your products direct?

  • We sell our products direct to Original Equipment Manufacturers and Distributors. If you are a Hospital or some other end user then we ask that you contact us for a referral.

2) Can I purchase online?

  • We do not currently offer an e-commerce option to our website. If you prefer to purchase online then we ask you contact us for a referral to one of our e commerce partners.

3) What is the “standard” size for a fitting?

  • There is no “standard” size. We offer fittings and connections based on the specifications established by the Compressed Gas Association (CGA) and National Pipe Thread (NPT). Our quick-connect and international fittings product lines are based on their respective original designs.

4) What is your warranty?

  • We warrant all the parts sold hereunder for one year from the date of shipment to be free from defects in material and workmanship as well as to conform to our written specifications to the parts. Please note the distinction between “defects” and “damage” as used in this warranty: defects are covered because we, the manufacturer, are responsible: however, we have no control over damage caused by such things as misuse or improper installation. Please refer to our Warranty and Remedy document for more details.

5) What does DISS stand for?

  • The Compressed Gas Association (CGA) developed the Diameter-Index Safety system (DISS) to establish a standard for non-interchangeable, removable connections for use with Medical Gases, Instrument Air, Vacuum (Suction), and WAGD (Waste Anesthetic Gas Disposal). Non-interchangeable indexing is achieved by a series of increasing and decreasing diameters in the components of the connections. These specific diameters act in key-like fashion, so that fittings within the gas service "family" will connect only with their own "family members." In place of diameter indexing, Oxygen (DISS 1240) has been assigned the long established 9/16"-18 thread connections as its safety standards.

6) What are the unique benefits of Bay Corporation’s gas fittings?

  • We take great care to design, engineer and manufacture all of our gas fittings to exacting tolerances. We pay special attention to detail in our craftsmanship and the results produce a superior quality fitting, one that you would be proud to install on your medical gas equipment or at your hospital.

7) When should a gas connector be replaced?

  • All medical gas fittings and connections should meet current standards for proper gas identification and safety. You should never “rig” a system outside the accepted standards. All fittings and connections that are improperly used should be replaced immediately. All fittings and connections that show all wear and tear should be replaced immediately. Please contact us with any questions and/or concerns.

8) Can your fittings be repaired?

  • All of our products are designed to be non-repairable, including our line of quick-connects, international fittings and hose assemblies. This feature is for safety reasons.

9) What can you tell me about Conductive and Non-conductive hose?

  • Bay Corporation manufactures and sells both Conductive and Non-conductive medical-grade hose products.  Conductive hose was developed at a time when flammable anesthetic gases were used in an effort to help ground medical devices as well as to help eliminate accidents caused by these same gases in the operating room. Today, the medical industry has eliminated the use of flammable anesthetic gases in most medical facilities around the world and yet, the use of Conductive hose remains a popular choice of medical facilities for its added layer of safety.  While we cannot offer an official recommendation, it is our opinion that the selection of hose product be based on where and how the hose product is used.  For reference only, our Conductive hose meets the conductivity requirement that was specified in NFPA 99:2005.

10) What is the difference between a Demand Valve and a Check Valve?

  • Demand Valves are also known as "Demand Check Units" as well as "DV's." These valves are opened when a mating connection is made as noted in the diagram below.




  • Check Valves are also known as "One-Way Check Valves" as well as "CV's." These valves are opened when gas pressure is present and it activates the valve as noted in the diagram below.
