What the government is buying

The Department of the Navy, through NAVSUP Weapon Systems Support Mechanicsburg, is soliciting offers for TAILPIECE,UNION — a plumbing and pipe fitting component. This falls under Federal Supply Classification (FSC) 4730, which covers pipe fittings and valves. The item is likely a union-type tailpiece used in fluid systems aboard naval vessels or at shore facilities, serving as a detachable connection point in piping systems.

NAICS code 332919 corresponds to "Other Metal Valve and Pipe Fitting Manufacturing." This classification includes manufacturers of industrial pipe fittings, unions, couplings, and related components made from metal. Companies in this space typically serve aerospace, defense, marine, and industrial markets with precision-machined parts meeting stringent material and performance specifications.

No set-aside program is indicated for this procurement, meaning it is full and open competition — all responsible sources, regardless of business size, may submit offers.

Key facts

Who can bid

This solicitation is open to all responsible offerors — small businesses, large businesses, veteran-owned, women-owned, and other concerns alike. No socioeconomic preference applies.

To bid, your firm should:

• Be registered in SAM.gov with active status
• Hold valid NAICS 332919 in your SAM profile (or demonstrate capability in pipe fitting manufacturing)
• Meet any defense subcontracting or supply chain security requirements typical of Navy procurements
• Be capable of producing parts to military specifications or defense standards commonly applied to shipboard components

If you are a small business, note that competing against larger manufacturers without a set-aside means your competitive edge will come from pricing, technical merit, and responsiveness rather than preferential evaluation.

How to put together a competitive bid

For a hardware item like this, the Navy typically evaluates on price and technical acceptability or lowest price technically acceptable (LPTA) basis. To strengthen your bid:

Understand the technical requirements. The tailpiece must meet specific dimensions, material specifications (likely bronze, stainless steel, or other corrosion-resistant alloy for marine environments), and pressure ratings. See the solicitation documents for the exact specification — this may reference a military standard, NSN detail drawing, or performance specification.

Verify your manufacturing capability. NAVSUP WSS manages spare and repair parts for weapon systems; quality and traceability are paramount. Ensure your quality system can support ISO 9001 or AS9100 standards if required, and that you can provide material certifications and test reports.

Pricingstrategy. Review historical pricing for similar FSC 4730 items if available. Consider whether this is a single-item purchase or if the solicitation includes quantity options or minimums — see the solicitation for exact quantities and any economic order quantity provisions.

Lead time and delivery. The Navy values reliable delivery for ship maintenance schedules. Highlight your production capacity and any expedited processes.

Past performance. If you have supplied to NAVSUP WSS, DLA, or other Navy activities, emphasize this. First-time suppliers should demonstrate relevant commercial or defense experience with similar fittings.
