Industrial 83336 SL-32 Grease Injector Centro-Matic

Centro‑Matic SL-32 Grease Injector, model 83336, is a multi‑outlet injector assembly used in Lincoln Centro‑Matic automatic lubrication systems to deliver precise amounts of grease into a single‑line circuit. Variants 83336‑1 through 83336‑4 provide from one to four injectors, with the -4 version including a manifold for multiple injectors; standard body material is carbon steel, with stainless variants available in other SKUs. The unit features a 1/4" NPTF inlet and a 1/8" O.D. injector outlet, and output is externally adjustable, verified by an indicator stem during operation. Operating pressure ranges from 1,200 to 3,500 psi (typical around 1,500 psi) and it is designed to dispense petroleum‑based lubricants with viscosity up to NLGI No. 2; it can be used in circuits alongside other SL‑32 injectors.
