Replacement Parts & Accessories
Gun tips, mix chambers, O-ring kits, pump repair kits, and heated hose components for Graco and PMC rigs — stocked in Canada with same-week shipping so a worn part doesn't turn into a week of downtime.
Downtime Is the Real Cost of a Worn Part
A $40 O-ring kit sitting in your truck box beats a $4,000 lost job day every time. Most rig downtime traces back to a small number of predictable wear items — gun mix chambers, proportioner pump seals, hose heat components, and filters — and crews that keep a basic parts inventory on hand rarely lose a full day to a repair that should have taken twenty minutes.
We stock parts across both major proportioner platforms with same-week shipping to Canadian addresses, plus rush options for a rig that's down mid-job. Compatibility is always confirmed against your specific proportioner and gun model before an order ships.
The most efficient contractors we work with treat parts inventory as a scheduled task, not a reaction. A basic spares box — spare mix chamber, O-ring kit, a couple of inline filters, a heat-trace splice kit — costs a few hundred dollars and lives in the truck permanently. Compare that against the cost of a full crew standing idle for a day while a part ships, and the math on carrying spares stops being a question.

Heated Hose & Rig Support Parts
Heated Hose Repair Components
Heat-trace splice kits, coupling ends, and insulation jacket sections so a damaged section doesn't mean scrapping the whole run.
Filters
Inline chemical filters that protect gun and pump internals from contamination — a cheap safeguard against a much more expensive mix chamber failure.
Transfer Pumps
Drum-to-proportioner transfer pump units and rebuild kits for keeping chemical flowing reliably from stock drums into the day tank.
Drum Heaters
Band and blanket-style drum heaters that bring cold chemical up to spray-ready viscosity before it ever reaches the proportioner — essential kit for winter jobs.
Building a Spares Kit for Your Rig
Not every rig needs the same spares kit, and over-stocking a truck box with parts you'll never use ties up cash just as surely as running short strands a crew mid-job. A sensible starting point is a two-tier kit: a day-to-day tier that rides on the truck permanently, and a deeper tier that lives at the shop or in a second vehicle for jobs where a supply run isn't a quick option.
The day-to-day tier should cover the parts that fail without much warning — a spare mix chamber and O-ring set for the gun, a couple of inline filters, a whip hose, and a small selection of fuses or fittings specific to your generator. These are the failures that stop a crew cold and have no field workaround, so they belong on the truck regardless of job type or season.
The deeper tier scales with how far you are from same-week delivery and how harsh the season is. Remote and northern contractors, or anyone spraying through a Canadian winter, should add a heat-trace splice kit, a spare drum heater band, and a pump seal kit to that second tier — freight delay risk and cold-weather failure risk both compound the farther you are from a supply hub. Crews working close to a major centre with reliable next-day freight can run a lighter deeper tier and lean more on rush shipping when something bigger fails.
Whatever the tier split, label and inventory the kit per rig rather than per truck — a mixed, unlabeled parts drawer is how a crew ends up digging through three bins on a jobsite trying to find the one O-ring that actually fits the gun on hand.
Same-Week Shipping, Rush Options for Downed Rigs
Standard parts orders ship same-week to addresses across Canada, with most urban centers seeing delivery well inside that window. When a rig goes down mid-job, rush shipping options exist specifically to get a critical part — a mix chamber, a pump seal kit, a heat-trace splice — back on-site as fast as freight allows rather than losing days waiting on a standard order cycle.
Active contractor accounts can also set up a standing spares inventory list with us so reordering common wear parts is a one-line request instead of rebuilding a parts list from scratch every time something fails. See shipping & delivery for regional timelines and freight zones.
Compatibility mismatches are the most common cause of a wasted parts order — an O-ring kit built for one proportioner generation installed on a slightly different model, a mix chamber sized for the wrong orifice. Send us your proportioner and gun model (or a photo of the nameplate if you're not sure) before ordering and we'll confirm fit before anything ships, which saves a second freight cycle and a second day of downtime.
Parts Category Comparison
| Product | Wear Interval | Field-Serviceable | Downtime Risk if Ignored |
|---|---|---|---|
| Gun Tips / Mix Chambers | 500–800 hrs | Yes | High — poor spray pattern |
| Pump Repair Kits | By hours / chemical type | Shop-preferred | High — ratio drift, leaks |
| Heated Hose Components | Seasonal inspection | Yes (splice kits) | High — cold-weather ratio issues |
| Filters | Per manufacturer spec | Yes | Moderate — protects downstream parts |
| Drum Heaters | Seasonal / as-needed | Yes | High in winter — cold chemical viscosity |
Parts & Accessories FAQs
Can I get emergency/rush delivery on parts if my rig goes down mid-job?+
Yes — rush shipping options are available for critical parts like mix chambers, pump seal kits, and heat-trace splices when a rig is down mid-job. Contact your account rep or our support line directly to arrange expedited freight.
Are your parts compatible with both Graco and PMC equipment?+
We stock parts across both major proportioner and gun platforms. Compatibility is always confirmed against your specific model before an order ships to avoid a mismatched part showing up on a jobsite.
How often should I expect to replace gun mix chambers and O-rings?+
Typical wear intervals run 500–800 spray hours depending on chemical type and duty cycle, though crews running heavy daily volume should inspect more frequently and keep a rebuild kit on hand rather than waiting for a failure.
What causes ratio/off-ratio spraying issues and how do I troubleshoot it?+
Worn gun mix chambers, degraded pump seals, and cold or inconsistent hose temperature are the most common culprits. Working through gun and pump wear parts before assuming a chemical issue resolves most off-ratio complaints.
Do you sell drum heaters for winter jobs?+
Yes — band and blanket-style drum heaters bring cold chemical up to spray-ready viscosity before it reaches the proportioner, which is essential equipment for any Canadian crew spraying through the colder months.
Is there a minimum order quantity for parts?+
No minimum on most individual parts and kits. Active contractor accounts can also set up a standing spares list for faster reordering of the parts your crew wears through most often.
