O-Ring

PSC 5331 relates to O-rings, which are critical sealing components used across various military, aerospace, and industrial applications. These precision-engineered elastomeric components are essential for creating leak-proof and pressure-resistant seals in mechanical systems, particularly in aircraft, naval vessels, and defense equipment. O-rings are manufactured to strict military specifications and are used in diverse environments ranging from maritime operations to aerospace platforms.

The federal contract awards in this category demonstrate a robust procurement landscape, with contracts ranging from small purchases under $100 to larger awards approaching $50,000. Multiple federal agencies, particularly the Defense Logistics Agency (DLA) and U.S. Coast Guard, are frequent purchasers of O-rings. Key contractors include Collins Aerospace, Noble Supply & Logistics, and various small businesses like DBR Industries and Phoenix Systems Engineering. Most contracts are firm fixed-price delivery orders or purchase orders, typically not set aside for specific business categories. Contracts frequently support maintenance and repair of military aircraft such as the MH-65 and HC-144, with performance locations spanning manufacturing facilities across the United States and delivery destinations including military logistics centers.

Recent federal contract opportunities continue this pattern, with solicitations from the Naval Supply Systems Command and U.S. Coast Guard seeking O-rings for military equipment. These opportunities emphasize stringent technical requirements, including compliance with military standards like MIL-STD-130 and MIL-STD-1330. Vendors must provide detailed documentation, meet precise manufacturing specifications, and often undergo 100% production lot testing at facilities like the Naval Surface Warfare Center. The opportunities are typically open to all responsible sources, with some noting potential small business participation, and require vendors to demonstrate capability in producing high-precision sealing components for military and maritime applications.
