354_Seal Specifications.docx

This is a technical specifications document for rubber seal assemblies required for dam gate applications under solicitation W19EP26QA015. The document details specifications for S-354 seal sets, which are required for two complete gate units. The S-354 seal assembly consists of three components: side seals (two units at 8 feet 9 inches in length with P-shaped profile), a top seal (23 feet 9¾ inches in length with P-shaped profile), and a bottom seal (23 feet 4 inches in length with rectangular 4" x 1" profile). All seals feature specific dimensional requirements including overall widths of 5 inches, overall heights of 1 inch, and various bulb and corner radii specifications. Both top and side seals require Teflon cladding, and rubber seal corners must be carefully fitted, spliced, and vulcanized at the time of manufacture prior to shipping.

The broader solicitation (W19EP26QA015) issued by the U.S. Army Corps of Engineers Jacksonville District requests quotations for five total dam gate seal assembly sets: three S351 seal sets and two S354 seal sets. The materials must meet specific technical characteristics including a durometer of 60-70, tensile strength of 3000 PSI, elongation of 450% minimum, modulus of 900 PSI, compression set of 30%, water absorption of 5%, and low temperature brittleness with no cracks. Seals must be packaged in protective wooden crates for shipment to Clewiston, Florida. Questions are due by July 24, 2026 at 9 AM EST, with responses due by July 31, 2026 at 9 AM EST.
