IWDC Member Distributors assure you and all customers of quality products, dedicated local service, product expertise, and vast inventories to supply every need. All IWDC Member Distributors are locally owned independent businesses that are involved in your communities – ensuring that local dollars are kept local.

Locally Owned – Internationally Known

These locally owned independent distributors are part of the IWDC Cooperative with over 800+ locations servicing North America (the United States, Canada, and Mexico).


IWDC Member Distributors service a multitude of industries such as construction, medical, specialty gases, welding, oil & petroleum, fabrication, and agriculture. There are many more industries we service. If in doubt as to whether we service your industry, please contact your local IWDC Distributor.

IWDC Members each own a voting share, and the cooperative is governed by bylaws filed in the State of California. In addition to having a staff that manages day-to-day operations, a Board of Directors made up of Member principals provides oversight and stewardship.
The IWDC has, at any given time, a dozen or so active Committees that are formed to tackle ongoing business opportunities. Member personnel serve with the IWDC staff on these Committees, and ideas flow back and forth between the Committees and our entire membership.

Primary IWDC Committees include those devoted to:

Marketing & Purchasing – Focuses on key vendor programs, IWDC’s brands, Web-based initiatives, and Volume/Growth/Rebate Agreements with key Vendor partners.

PurityPlus Program – The PurityPlus program has a Steering Committee that helps direct the Program initiatives along with its four sub-committees: PurityPlus Marketing, PurityPlus Operations, PurityPlus Vendor Relations and PurityPlus Training.

Gas Committee – Focuses on leveraging Product Supply agreements, extend product line offerings, services and training and to form strategic partnerships with select gas vendors.

Besides opportunities provided by serving on Committees or the Board, the IWDC has two annual meetings that provide terrific networking and best-practice sharing opportunities: our Sales & Purchasing Conference and our Owners' Meeting.
