Graco SDM18/SDP18 Flexible High-Flow Nozzle & Extension Kit #255858
The Graco #255858 is the flexible version of the high-flow oil/antifreeze nozzle kit for the SDM18 and SDP18 meters — same non-drip, quick-close action as the rigid 255857, with a flexible section that reaches fill tubes and awkward angles a rigid nozzle cannot. Tight engine bays and crowded service pits are exactly its job.
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 fitment either way: 255858 (this kit) flexes into fill tubes and tight bays; the rigid 255857 is the straight shot. The meter compatibility is identical, so choose by geometry, not price.
Does it fit the SDV15 valve?
Yes — the SDV15 accessory table lists 255858 alongside the rigid version (p.110), so valve-based high-flow stations take the same nozzle in either extension style.
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.
