No Safety Data Sheet on file.
CarCareTruth has not received a Safety Data Sheet from the manufacturer for this product, so no GHS hazard classification can be cited. The tiers below are cautious defaults — “Beyond SDS” — translated from the product’s ingredient chemistry and how comparable formulations classify, not from a manufacturer hazard classification. Request an SDS from the manufacturer before use.

Translated from the product label
Product label states 'CAUTION: Eye Irritant.' No formal SDS to confirm H-code classification. Situational eye protection consistent with the eye-irritant label warning during Plug Bond application.
No Safety Data Sheet is on file for this product. The tier above is a cautious default translated from the ingredient chemistry, not a cited manufacturer classification. Request an SDS from the manufacturer before use.

PPE tiers here are cautious defaults translated from the product’s ingredient chemistry — no manufacturer SDS is on file to cite. Not professional safety advice. How we report safety.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.
No warranties. CarCareTruth makes no warranties, express or implied, and expressly disclaims the implied warranties of merchantability and fitness for a particular purpose.

TL;DR Broadly trusted by owners, with many documenting lasting repairs · some report driving thousands of kilometers post-repair with no pressure loss. Note: this kit plugs the hole but does not inflate the tire; a separate compressor is always required.
The Slime 20290-1 Pro Series is a 13-piece manual plug kit for tread-area punctures on tubeless tires: aluminum T-handle reamer, aluminum T-handle plugger with insertion collar (sets correct plug depth automatically), 10 heavy-duty rubber plug strips, and a tube of Plug Bond adhesive. The process takes under five minutes once you have a compressor handy: ream the hole, thread a plug strip, apply adhesive, insert to collar depth, trim flush. Community evidence is consistently positive · multiple owners document months to years of hold time including off-road use. The 4.5-inch reach handles larger SUV and ATV tires. Not usable for sidewall damage.
Good fit for drivers who want a reusable, quality repair kit in the trunk, go-bag, or ATV kit. The aluminum tools are a step up from plastic-handled alternatives. Skip it if you need a single-product flat-tire solution · you will need a separate inflator alongside this kit.
The Plug Bond adhesive label carries a "CAUTION: Eye Irritant" warning; per sibling product documentation the formula is water-based. No formal SDS has been sourced, so specific hazard code classifications are unconfirmed. The product listing flags a Proposition 65 warning; the likely trigger is carbon black in the rubber plug strips based on sibling product analysis. No propellant, no pressurized-can disposal, water-based adhesive · considerably lower environmental footprint than an aerosol sealant.
CarCareTruth scores Slime 20290-1 Pro Series Ultimate Tire Plug Kit at 7.1 out of 10 on the composite CCT score, with a health sub-score of 5.0/10. The CCT score blends real-world effectiveness, ingredient health impact pulled from the manufacturer's safety sheet, and environmental footprint against a published category rubric. See the methodology link on this page for the full scoring breakdown.
Per the Safety Data Sheet ingredient disclosure: No SDS sourced. Per 1034-A sibling product instruction card: Plug Bond contains Water, Polyvinyl Alcohol, Polyethylene, and Calcium Carbonate. Not confirmed via formal SDS for this SKU.
