Graco SDM18/SDP18 Rigid High-Flow Nozzle & Extension Kit #255857
The Graco #255857 is the genuine high-flow, non-drip, quick-close rigid nozzle with extension for oil and antifreeze, built for the SDM18 and SDP18 — the 18 gpm-class meters that fill fast. Graco also lists this nozzle in the SDV15 control valve's accessory table, so valve-based high-flow stations use it too.
Where Graco Lists This Kit
- SD Electronic Meters — nozzle and extension kits (catalog p.101): SDM18/SDP18, oil/antifreeze
- SDV15 control valve accessories (p.110) — high-flow nozzle position
- Preset meters — PM20 accessory table (p.99)
Questions Shops Ask
Rigid or flexible — which one?
Same high-flow fitment either way: 255857 is rigid, 255858 is flexible. Choose by fill geometry — the flexible reaches fill tubes and awkward angles in tight engine bays; the rigid is the straight shot. The meter fitment is identical, so the price difference is not a fit question.
Does it fit the SDV15 valve?
Yes — Graco lists 255857 (and the flexible 255858) in the SDV15 control valve accessory table (p.110), so a valve-based high-flow station takes the same nozzle.
How do I match a nozzle to my meter?
Match two things: the meter family (SDM8/SDP8 take the 8 gpm-class nozzles; SDM18/SDP18 take the high-flow) and the fluid (oil/antifreeze versus gear lube). If your meter is a preset or valve station instead, the same part numbers appear in those accessory tables — call (817) 865-3707 with the station and we will match it.

Fitment & Setup
Fits SDM18 and SDP18 meters (and the SDV15 valve's high-flow nozzle position) for oil and antifreeze. Not the 8 gpm-class SDM8/SDP8 family — match the nozzle to the meter and fluid before ordering.
