Frequently Asked Questions

+How do I know which replacement parts fit my Samurai tool?

Every part is tied to a specific part number in your ST-235 or ST-358 owner's manual — check your manual's parts diagram first, or send us your tool's serial number and we'll match the right part for you.

+What replacement parts are available for my Samurai tool?

We stock the full range of wear components for both tools — bearings, seals, O-rings, valves, gaskets, and spindles — each corresponding to a part number in your owner's manual. If it's in your manual's parts diagram, we carry it.

+Can I install these parts myself?

Yes — both tools ship with spanner wrenches for exactly this kind of maintenance, and your owner's manual walks through disconnecting air and water before swapping any part. No specialty tools required beyond what's already in the box.

+How fast do replacement parts ship?

[CONFIRM: standard processing/shipping timeframe.] We know downtime costs you money, so orders go out as quickly as we can get them there.

+Are replacement parts covered under warranty?

No — the 1-year warranty covers manufacturing defects only, not wear and tear. Replacement parts exist because normal use wears these components down over time, and that's expected, not a defect.

+What if I can't find the part I need?

Contact us directly at (877) 413-4266 — every part number in the ST-235 and ST-358 manuals is something we can source, even if it's not listed on the site yet.
