Graco SDP18 Electronic Preset Oil/Antifreeze Meter, Flexible, 1/2" NPT #26C357
The Graco #26C357 is the SDP18 preset meter for shops that portion oil at fill points that do not line up with the hose: the flexible extension bends around shrouds, braces and dress covers to reach recessed fill necks, while the meter counts in pints, quarts, gallons or liters (factory-set to quarts) at flows to 18 gpm. It is Pulse FC-enabled for fluid security on expensive drums.
It fits heavy-duty dealerships, fleet garages and equipment shops running preset dispensing on oil — and the SDP18 line is rated for oil, ATF, gear oil and antifreeze service overall, with this configuration being the high-flow oil version (18 gpm).
Where It Fits
- Threads onto a standard 1/2 in. NPT bulk oil hose
- The outlet is a 3/4 in–16 straight-thread O-ring boss that accepts SD-series nozzle assemblies — this configuration ships with the high-flow oil nozzle (replacement part 255461)
- Rated for petroleum- and synthetic-based crankcase oil, ATF and gear oils (antifreeze and windshield-wash service are on other SD-series models)
- The flexible extension is replaceable (part 16Y863) per the SD-series repair manual
Questions Shops Ask
Can one meter cover oil and coolant?
The SDP18 line is rated for oil, ATF, gear oil and antifreeze service, but this configuration ships with the high-flow oil nozzle at 18 gpm. For antifreeze preset dispense, Graco's antifreeze-nozzle models (26C355 flexible / 26C385 rigid) run at 8 gpm — call us and we will match the right one to your coolant bulk line.
Why flexible over the rigid 26C356?
Same meter, same preset control — the bendable extension gets the nozzle into recessed fills while the display stays readable.
How accurate is it?
Graco rates SD-series dispense accuracy at ±0.5% — tested at 2.5 gpm, 70°F, with 10-weight oil and 1 gallon dispensed. Flow rates are tested in 10W motor oil and vary with fluid pressure, temperature and viscosity; the meter can be calibrated to your fluid and pressure.
Why Buy from Alamo
- We stock the service parts that keep a meter in service — nozzles, extensions, swivel/filter kits and O-rings covered in the SD-series repair manual — so a dropped nozzle does not shut down a stall.
- We confirm your hose, inlet size and fluid list before the order ships, so the meter threads onto what is already on your wall.
- Call (817) 865-3707 and we will match the right SD-series meter to your bulk room.
Fitment & Setup
This configuration is the high-flow oil version (18 gpm). The SDP18 line carries Graco's oil/antifreeze designation and the meter is rated for oil, ATF, gear oil and antifreeze — but antifreeze preset dispense runs on the antifreeze-nozzle models (26C355 flexible / 26C385 rigid) at 8 gpm. Confirm your inlet size and fluid list before ordering. If your dispense points are all straight-line drops, the rigid 26C356 is the simpler setup.
