A tube fitting might look like a SWAGELOK Tube Fitting. You might even be told it& a "SWAGELOK" Tube Fitting. But ifyou are not buying from an Authorized SWAGELOK Sales and Service Representative, itb probably not a Genuine SWAGELOK Tube Fitting. You ΊΙ be offered many imitations at lower prices, prices which neither reflect true in-service performance costs, nor match the SWAGELOK Tube Fitting standards for leak-tight integrity, ease of installation, availability and service. There is only one way to assure yourself of Genuine SWAGELOK Tube Fitting performance. Buy from an Authorized SWAGELOK Sales and Service Representative.
