Foster 210-17 is a 1/4" body ARO 210 interchange air plug with a 3/8" Hose Barb end, plated steel body. Rated 300 PSI.

The ARO 210 interchange (1/4" body) is the second most common air fitting profile in US shops after the industrial style. This plug fits ARO 210 style couplers only, including every Foster 210 Series coupler; it does not fit industrial, Lincoln or Tru-Flate couplers. The plug is unvalved; the coupler does the shut-off.

Made in the USA by Foster to industrial spec. Machined from solid bar stock with a hardened, plated finish, this is the plug professional shops run on compressors and air tools, not a soft import that rounds off and leaks.

OUR VERDICT

A standard 1/4" industrial interchange plug. This is the plug most US air couplers accept. Check your coupler style before ordering; if it is an ARO or Tru-Flate coupler, it needs a matching plug or a universal coupler.

WHAT WE LIKE
  • Made in the USA by Foster, heavy-duty industrial grade
  • ARO 210 interchange, fits ARO 210 style couplers
  • One-piece plated steel or brass body
  • Available in NPT, hose barb and push-on ends
WORTH NOTING
  • ARO 210 only; it will not fit industrial, Lincoln or Tru-Flate couplers
  • Steel plugs will show surface rust outdoors; use brass there
