2.5" nathan monitor injector

Expected late 2019
(updated 5/21/19)

Eccentric Engineer is very proud to announce the first super detailed injector ever produced in 2.5" scale.

The Monitor injector was found on countless narrow gauge locomotives across America, and this 2.5" scale version is uncompromising in detail and performance.

Delivering 6 pints per minute (45 gallons per hour), this injector is capable of meeting the demands of the larger boilers found on narrow gauge locomotives. The extra capacity compared to the Standard Injector (or SuperScale/Ohlenkamp) is pleasantly noticeable.

The steam and primer valve feature triple lead threads for very quick opening. The steam valve requires 1 full turn, and the primer valve needs to only be cracked open.

The primer valve handle is broached with a hexagon so it can be conveniently positioned to suit your installation.
