Overview
Stem replacement kit for the trigger valve on the Sapphire Scientific Clear-View Upholstery Pro (AW59). Sapphire part number 48-064, OEM code 108419. It replaces SS-S13-01704.
This kit has the high-pressure PTFE seat. It also suits a PMF V4N valve, and is an alternate for PMV124V5B and PMV300B.
What it does — and what it does not
Sapphire's user instructions for the Upholstery Pro give two repair options when the trigger leaks or will not release enough solution:
- Option A — rebuild the valve. That is this kit (48-064). Remove the trigger lever nut and bolt, unscrew the stem retention nut, lift out the stem assembly, fit the new one, and reassemble using the new lock nut supplied.
- Option B — replace the whole valve. That is assembly 23-070, a bigger job involving the solution outlet tube and the inlet hose.
Try Option A first. It is the cheaper repair and it is the one Sapphire list first.
Before you assume it is the valve
Sapphire are explicit about this: check the glide first. Their instruction is to satisfy yourself the glide is not plugged or damaged before concluding the trigger needs service.
A tool that is not releasing enough solution can equally be:
- a plugged glide
- a blocked inline strainer (part 20-006, behind the hex nut on the flow adjust assembly)
- a blocked or wrong orifice plate (20-035)
All three are quicker to check than a valve rebuild.
Sapphire's own user instructions for the Upholstery Pro (document 07-01713B) are clear that this tool is designed to be serviced in the field with basic hand tools in a few minutes. That is worth taking them up on — an upholstery tool that has gone off is usually a five-minute job, not a new tool.
