The Kadee 850 is a package of precision-engineered metal centering springs that fit all Kadee O Scale couplers. Centering springs bring the coupler back to center after it deflects on curves and through turnouts, which keeps couplers lined up for clean, reliable coupling across a train. Part 850 provides genuine Kadee replacements to keep O Scale rolling stock operating smoothly.

Each package of part 850 contains one dozen springs and works with Kadee #740, #742, #743, #745, #746, #747, #800, #801, #804, #805, #806, #816 couplers and the #812 coupler height gauge. Made in the U.S.A. from phosphor bronze, the springs measure 0.110" outside diameter, 0.096" inside diameter, 0.007" wire, about 0.218" free length, with 7 total coils. The #241 Dual Tool is recommended for installation.
