Quick Verdict
Two brass 1/4" NPT air hose fitting kits face off: the 10pc Brass Air Hose Fittings Quick Connect Plug Coupler at USD 10.09 and the 14pc Air Hose Fittings M/D Type Quick Connect Kit at USD 15.99. The 10-piece kit is the lower-priced option and gives you a set of industrial quick-connect plugs. The 14-piece kit costs more but brings a larger assortment that pairs couplers with plugs. If you want to keep the upfront spend down while equipping tools with plugs, the 10-piece set is the straightforward pick. If you want a more complete air-hose fitting package in one purchase, the 14-piece kit is the better match.

Where Each Kit Wins
Choose the 10pc Brass Plug Coupler when you want the lower listed price and the tools you use already have compatible couplings on the hose side. The set contains ten quick-connect plugs, so you can swap tools on and off the line without shutting down the compressor.
Choose the 14pc M/D Quick Connect Kit when you want a larger kit that includes both couplers and plugs. It carries a 300 psi max pressure rating, so it brings an extra spec for shop-air setups.
Product Notes
10pc Brass Air Hose Fittings Quick Connect Plug Coupler
The 10-piece set includes ten industrial quick-connect plugs in 1/4" NPT male form and solid brass construction. One concrete reason to choose it is the lower listed price next to the 14-piece kit. The trade-off is the focused piece count: this set contains plugs, while the larger kit pairs couplers with plugs. If your hose ends already have couplers, this plug-only assortment may cover your needs without paying for parts you don't use. The brass build is a shared feature with the other kit, so the real decision comes down to how many parts you need and how much you want to spend.
14pc Air Hose Fittings M/D Quick Connect Kit
This larger kit combines quick-connect air couplers and plugs in a 1/4" NPT M/D type configuration. It has more pieces, so it can be a convenient single purchase for outfitting air hoses, compressors, nailers, blow guns, and pressure washers. It also comes with a 1-year manufacturer warranty. The limitation is the higher listed price: you pay more upfront for the larger assortment. If you don't need a combined coupler-and-plug set, the 10-piece kit gives you the simpler, lower-cost route.
Final Choice by Use Case
For a quick plug replacement kit at the lower end of the price range, the 10pc Brass Air Hose Fittings Quick Connect Plug Coupler is the right call. For a more complete air-line setup with a bigger selection of parts, the 14pc Air Hose Fittings M/D Quick Connect Kit makes the extra spend easier to justify. Choose based on your workbench: spare plugs for tools you already own, or a broader kit that can handle new hose-end and tool-side connections.
