1140 PowerFill Adapter – 1/4" NPT Quick-Connect Fitting

The Motive Products 1140 PowerFill Adapter expands the reach of your Motive PowerFill system to any fluid port with a 1/4" NPT thread. Thread this precision fitting into a gearbox fill plug, differential cover, cooling-system port, or hydraulic reservoir, snap the stainless quick-connect to your PowerFill hose, and fill one-handed — no funnels, no spills, no second person holding the bottle. The CNC-machined body and chemical-resistant O-ring seal keep the connection leak-free across dozens of fluid types and hundreds of service cycles.

Specifications & Features

  • Thread Size: 1/4" NPT male — fits transmission fill plugs, differential covers, cooling ports, and aftermarket hydraulic fittings
  • Stainless Quick-Connect Nipple — snaps to any Motive PowerFill or Power Bleeder hose; releases cleanly for tool-free adapter swaps
  • Chemical-Resistant O-Ring — safe with gear oil, ATF, coolant, and brake fluid; no swelling or leaking on synthetic fluids
  • Compact CNC-Machined Body — fits tight engine bays and under-car pockets where funnels and bulky fittings can't reach
  • USA-Made & Rebuildable — precision threads and replaceable O-ring seals guarantee years of shop use
