Product Details

The Dorman 490-071.1 is a square head pipe plug featuring a 1/4-inch Male National Pipe Taper (MNPT) thread. Designed as a direct OE replacement, this plug matches the original equipment part for diameter, thread pitch, and head type to ensure a precise, reliable fit.

Key Features:

  • Square head design for easy installation and removal with standard tools
  • 1/4 in. MNPT (Male NPT) thread — standard 1/4-18 NPT pipe thread specification
  • OE-matching dimensions — correct diameter, thread pitch, and head type for a proper fit
  • Corrosion-resistant construction engineered for long service life
  • Leak-free performance — manufactured to maintain a secure, tight seal
  • Validated through quality testing to ensure proper fit and function

This pipe plug is commonly used in automotive brake line repair, fluid system port sealing, and other underhood applications requiring a reliable threaded pipe plug. Dorman's 490-series pipe fittings are a trusted solution for both OE replacement and general repair use.

Great price

Autoplicity had a MSD Timing Twister that was discontinued and no one had in stock. I called 6 places before getting in touch with them. Ordered part and had it in a matter of days.

Awesome company! I can't believe the price for the rack I bought. The lowest anywhere!! On top of the killer price, the shipping speed was outstanding. I would definitely buy from these guys again!
