Two different type of O-Ring Gasket Seals

The Department of the Army Materiel Command Contracting Command Rock Island Arsenal has published a Special Notice regarding the procurement of two different types of O-Ring Gasket Seals for Hawk Missile systems at McAlester Army Ammunition Plant. Posted on March 25, 2026, this notice announces the Government's intent to issue a Limited Source Justification and conduct a sole source purchase order using simplified acquisition procedures. The procurement will be awarded under other than full and open competition as authorized by FAR 6.302-1. This is not a request for offers, and the Government reserves the right to decline proceeding with the procurement based on responses received.

The objective of this Special Notice is to identify a single authorized supplier capable of providing O-Ring Gasket Rubber Seals that meet the proprietary specifications required for existing Hawk Missile equipment systems. Jonal Laboratories Incorporated is identified as the only supplier currently authorized to manufacture these components, as it exclusively owns the proprietary drawings and specifications necessary to ensure uniform compatibility and performance with integrated defense systems. The deadline for submissions or inquiries is March 27, 2026, providing a two-day response window. Eligible parties should note that information submitted in response to this notice will be evaluated solely to determine whether future competitive procurements for this item should be conducted. Due to the proprietary nature of the product and the sole source justification, only suppliers meeting the specific technical and material requirements established by the Government may participate in any resulting procurement action.
