4 ounces is a single 29er tire, a pair of road tires, or one mid-season top-off on a mountain bike that's been sitting in the garage. Orange Seal's smallest refill bottle fits riders who don't need bulk quantities sitting on a shelf—first-time tubeless converts testing the waters, or anyone maintaining one bike without accumulating leftover sealant that ages past its shelf life. The compact size also packs easily for bikepacking trips or race weekends where a mid-event refresh might save an otherwise flat-prone stage.

The regular formula uses Orange Seal's standard latex base loaded with nanite particles—solid sealing material in various shapes and sizes that migrates toward punctures and coagulates around the breach. Sealing capacity handles punctures up to 1/4" and slices up to 3/4", covering thorns, glass, small nails, and the kind of sharp debris that tubeless is designed to shrug off without stopping. Temperature tolerance extends down to 11°F, making the formula viable for three-season riding in most climates.

Service life runs 30 to 45 days under normal conditions before the latex begins drying out and losing its sealing capability. Heat and low humidity accelerate that timeline; cooler, damper conditions extend it. The 4oz bottle handles one refresh cycle on a mountain bike or two on a road setup, which aligns with monthly maintenance intervals that keep tubeless systems reliable. If you're checking sealant regularly anyway, the small format means you're always working with fresh product rather than drawing from a bottle that's been open for months.... Read More
