Confidence: Verified for PCL PURITY FG product line and NSF H1 registration numbers; Inferred for CFIA / proAction framing language; Estimated for the typical PURITY-vs-conventional split on a 150–250 cow dairy.
Where PURITY FG applies on a SWO dairy
- Milking systems — pulsator vacuum pumps, milking line lubrication points, robotic milker articulations where lube could contact milk
- Feed handling — TMR mixer drive components above the mix chamber, feed conveyor bearings above feed
- Milk transfer pumps, plate cooler ancillaries
- Anywhere a lube failure (drip, fling, leak) could put non-food-grade oil into feed or milk
Regulatory framework
- NSF H1 registration — approved for incidental food contact. PURITY FG carries NSF H1 registrations across the line. Specific examples: PURITY FG AW Hydraulic Fluid 32 = #102588; AW 46 = #102589; AW 68 = #102590.
- CFIA expectations — the Safe Food for Canadians Regulations require food safety controls. The dairy-sector equivalent (proAction, Dairy Farmers of Canada) expects that any lubricant with food-contact potential is NSF H1 or equivalent.
- Allergen / kosher / halal — PURITY FG products are allergen-free; manufactured in a facility free of peanut/tree-nut handling; Kosher Pareve certified (Star-K); Halal certified (IFANCA); many products are ISO 21469 certified (hygiene requirements for the design, manufacture and use of lubricants in food, drink, pharmaceutical, cosmetic and tobacco industries).
Practical scope on a typical Oxford County dairy
A 150-cow tie-stall or 250-cow free-stall dairy in Oxford County has perhaps 8–15 lubrication points where PURITY FG genuinely matters and another 30–50 points where conventional grease is appropriate. Cost premium on PURITY FG vs. PRECISION XL EP2 is real — often 2–4× for grease, 1.5–2× for hydraulic — but the scope is bounded. The conversation is "where does this fluid go in the milking parlour and feed alley," not "replace everything."

PURITY FG products that fit ag-dairy
- PURITY FG2 Multi-Purpose grease (NSF H1, ISO 21469) — default for above-feed/milk bearings.
- PURITY FG AW Hydraulic Fluid 32 / 46 / 68 (NSF H1: #102588 / #102589 / #102590).
- PURITY FG Synthetic EP Gear Fluids — gearboxes above the food zone.
- PURITY FG Chain Fluid / Penetrating Spray / Silicone Spray — consumables for ongoing maintenance.
