Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 aspiration toxicity — thin, oily liquids can slip into the lungs if swallowed, causing chemical pneumonia.
If swallowed, inhaled, or splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.
About this product's hazards. This product's Safety Data Sheet uses signal word danger. Read the manufacturer's SDS and follow all safety instructions before use. CarCareTruth ratings translate the manufacturer's safety sheet. They do not replace the SDS or substitute for a hazard assessment specific to your task.
Health score is for adult use as intended, per the manufacturer's SDS. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.

From the manufacturer’s Safety Data Sheet, Section 8
“No H318 or H319 at SDS §2 mixture level. Aerosol mist near face during overhead or close-range spray is the specific trigger. Chemistry does not escalate to recommended · no eye-irritation or eye-damage classification at mixture level.”

From the manufacturer’s Safety Data Sheet, Section 8
“No H314 or H317 at SDS §2 mixture level; no H315 at §2 either. SDS §8 recommends chemical-resistant gloves for prolonged or repeated contact with the petroleum carrier. Brief incidental contact during home use is the low-exposure scenario.”

From the manufacturer’s Safety Data Sheet, Section 8
“H335 (respiratory irritation, STOT SE Cat 3) confirmed at SDS §2 mixture level. Aerosol form-factor multiplier ×1.5 applies · fine mist from aerosol application creates the primary inhalation exposure. H335 at §2 escalates lungs to recommended; use outdoors or in well-ventilated areas. SDS §7: 'Use only outdoors or in a well-ventilated area.'”

TL;DR DANGER-rated aerosol with a California Prop 65 warning · wear nitrile gloves and use outdoors or with real ventilation. With that caveat, it genuinely lubricates: community follow-up documents quiet hinges and cable sheaths for 2·3 months on one application, and the dry-film residue attracts less grit than plain petroleum-oil aerosols.
Tri-Flow lubricates and protects moving mechanisms · door hinges, window tracks, cable sheaths, bike chains, drawer slides. Aim the straw, spray a short burst, work the joint. The residue cures drier and less tacky than standard petroleum-oil aerosols, which is why community follow-up shows 2·3 months of effective lubrication before reapplication is needed. Grit accumulation is below average for this category, and the corrosion-inhibitor package protects stored tools and outdoor hardware.
Good fit for homeowners who want a hinge or track quiet for the season · not just the week. Skip it for regular enclosed-space use; choose a pump-spray or drip lubricant with lower VOC. Avoid on rubber o-rings and weatherstripping where a silicone-specific lubricant is safer.
PPE tiers are translated from GHS hazard codes · not generic SDS Section 8 boilerplate. DANGER from H304 (aspiration hazard · do not induce vomiting if ingested; seek medical attention), H335 (respiratory irritation), H336 (narcotic effects), and H373 (repeated-exposure organ toxicity). H222 and H280 are physical hazards only. Fine mist from aerosol application creates the primary inhalation exposure; H335 at mixture level escalates lungs to recommended · use outdoors or with ventilation. Prop 65 confirmed in SDS §15 (the product listing is a false negative). No PFAS in this formula. Environment score of 3 reflects petroleum-distillate aquatic toxicity, high estimated VOC, and a non-biodegradable carrier.
The DANGER signal word reflects four GHS hazard classifications in SDS Section 2. H304 (aspiration hazard · petroleum distillates can cause chemical pneumonitis if swallowed and enter the airways) is the primary health-tier driver. H335 (respiratory irritation) and H336 (narcotic effects) address inhalation from aerosol mist. H373 covers repeated-exposure organ toxicity from long-term overexposure. H222 (extremely flammable aerosol) and H280 (gas under pressure) are the physical hazards behind the fire and pressure warnings. Do not induce vomiting if ingested · seek medical attention immediately.
Yes. SDS Section 15 explicitly states: 'WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.' The warning is for aromatic hydrocarbons in the petroleum-distillate carrier · compounds in the naphthalene and benzene class. The product listing returned a false negative on the Prop 65 field; the SDS is authoritative.
No. The dry-film additive is tetrafluoroethene polymer (PTFE, CAS 9002-84-0) · a fully polymerized solid particle that is chemically distinct from per- and polyfluoroalkyl PFAS compounds. PFAS are reactive substances with long perfluorocarbon chains; polymerized PTFE solid particles do not carry that chemistry. SDS Section 3 lists no PFAS-classified ingredients.
Community follow-up across home-repair forums and long-term owner reviews documents 2·3 months of effective lubrication on household mechanisms · door hinges, window tracks, and cable sheaths · on a single application. The dry-film additive leaves a less tacky residue than plain petroleum-oil sprays, which is why grit accumulates more slowly and lubrication lasts longer. On high-cycle mechanisms like garage door hardware, reapplication around the 2·3 month mark aligns with community experience.
SDS Section 10 does not document specific material incompatibilities, and community experience over years of use on hinges, cables, and sliding mechanisms does not show widespread rubber or plastic damage at typical home-use exposures. For rubber o-rings, seals, or weatherstripping in prolonged contact, a silicone-based lubricant is a more conservative choice · silicone lubricants are specifically formulated for rubber-safe use.
