What the government is buying
The Navy's Naval Supply Systems Command (NAVSUP) Weapon Systems Support office in Mechanicsburg, PA is soliciting bids for a tailpiece, union — a hardware component used in piping or tubing systems. This falls under Federal Supply Classification 4730, which covers fittings and special items for hose, pipe, and tube applications commonly found in naval vessels and shore facilities.
NAICS 332919 covers other metal valve and pipe fitting manufacturing. Companies in this sector produce precision-machined metal components including couplings, elbows, tees, unions, and related fittings used in fluid systems. Tailpiece unions specifically connect sections of pipe or tubing where disassembly may be needed for maintenance.

Who can bid
This is an unrestricted solicitation with no small business set-aside, meaning businesses of any size may compete — including large manufacturers, mid-size firms, and small businesses. Companies registered in SAM.gov with NAICS 332919 in their profile are eligible to receive award.
Metal valve and pipe fitting manufacturers with experience supplying defense or marine applications may find this opportunity aligned with their capabilities. See the solicitation for any required certifications, quality standards (such as ISO or military specifications), or past performance requirements.
How to put together a competitive bid
For machined metal components in unrestricted NAVSUP competitions:
Review the technical specification for material requirements, dimensions, threading standards, pressure ratings, and surface finish — NAVSUP mechanical components often require exact conformance to military or federal specifications.
Verify your manufacturing capacity for the stated quantity and delivery schedule; naval supply contracts typically penalize late delivery.
Confirm supply chain readiness for raw materials (brass, stainless steel, or other alloys commonly used in marine unions) — lead times for specialty metals can affect pricing and delivery commitments.
Examine packaging and marking requirements — defense supply chains have strict labeling, traceability, and preservation standards.
Calculate total evaluated price carefully, including any shipping to the designated government destination; unrestricted competitions are typically lowest-price technically acceptable.
Check for applicable wage requirements such as the Davis-Bacon Act or Service Contract Act provisions if repair services are involved.
Ensure your SAM.gov registration is active and includes NAICS 332919.
See the solicitation for specific inspection requirements, first article testing provisions, and any approved sources or qualification requirements.
