Description

This General Electric 25C6388P07 carbon brush (aftermarket reference Repco REP3009) is a direct OEM-style replacement for GE brushed DC machines. The wafer is pressed from electrographite (supplier grade T573) — heat-treated carbon with a fully graphitic structure that gives low electrical loss, medium contact drop, and excellent performance at medium-to-high commutator speeds, with stable film formation and even wear. The square 1.25" × 1.25" cross-section suits holders built for large-contact-area DC machine duty.

Features & benefits:

OEM-matched dimensions — 1.25" × 1.25" × 3.25" (31.75 × 31.75 × 82.55 mm) wafer, drop-in fit for holders sized for GE 25C6388P07.
Electrographite material — low electrical loss, medium contact drop, low-to-medium friction, suitable for higher peripheral speeds.
4-1/2" flexible copper shunt — tinned braided lead with terminal, resists fatigue and keeps a stable connection to the brush box.
Cross-referenced part numbers — GE 25C6388P07, Repco REP3009.
Typical applications — GE DC motors and generators, medium-to-high speed commutator duty.
Quality-inspected before dispatch: dimensional check, lead crimp integrity, and surface condition per batch.
