The U.S. Coast Guard is seeking quotations for 1,200 units of a specific nonmetallic hose assembly (NSN: 4720-12-310-5413) used in ship bow thrusters, with Schottel GmbH as the mandatory Original Equipment Manufacturer (OEM). Using non-OEM components poses severe safety risks, and offers for "equal" products must meet strict physical, functional, and performance characteristics for government approval. All items must be individually packaged and marked per MIL-STD-2073-1E and MIL-STD-129R, with standard commercial packaging unacceptable. The contract will be awarded on an all-or-none, lowest price technically acceptable basis, and offerors must be registered in SAM with valid DUNS numbers. No budget amount or performance location is specified in the description.
