The one syringe here engineered to pass carbon fibers — and the smallest
SILCA Sealant injector, 59 ml, for SILCA sealant
A reusable 59 ml sealant injector engineered for SILCA’s fiber-loaded sealant, injecting through a Presta valve core.
What you are getting
The SILCA Ultimate sealant injector: a syringe holding 2 oz (59 ml), with a blue tip, a hose, and a plunger, for injecting through Presta valve cores. Reusable. $11.99.
Fifty-nine milliliters, for a one-liter bottle
SILCA sells its Ultimate sealant in 1,000 ml on this page, and its own injector holds 59 ml.
Against the rest of this shelf: Park Tool 100 cc, Thinvik 100 ml, Thinvik kit 100 ml. And the Thinvik listing supplies the reason three of four converge on that number: “one shot to get your MTB tires to around 100 ml”.
So a mountain bike tire is two pulls with this injector, and a liter bottle is seventeen fills. That is the oddest thing on the page: a brand selling the largest sealant bottle with the smallest syringe.
For a road tire, which takes far less, 59 ml is ample.
It is specified for SILCA’s own sealant, and that cuts both ways
“Designed to inject up to 2 oz of SILCA Ultimate Tubeless Sealant”, and “engineered for use with SILCA’s latex-based tubeless tire sealant with FiberFoam Technology”.
That is the one answer on this page to the question the Thinvik injectors raise. Both of those refuse “sealant containing large particles”, and SILCA’s sealant carries carbon fibers — so the manufacturer’s own syringe is the one tool here explicitly engineered to pass them.
The reverse is the limit: nothing on this listing says it handles any other brand’s sealant. The Park Tool TSI-1 claims “any injectable sealant”, for $28.90.
The instructions are complete, and the first step is a warning
“Connect the blue tip to the syringe tip, pushing hard — then draw the sealant into the syringe from the bottle, attach the hose to the valve system and push the plunger.”
Pushing hard is the kind of instruction that only appears after customers have failed to do it. A tip that is not fully seated leaks sealant over a wheel, which is precisely the mess the first bullet promises to avoid.
“Seals punctures up to 7.5 mm (0.30 in) and stays liquid for over 6 months.”
Both are properties of the sealant, not of the syringe — the SILCA Ultimate sealant on this page is where they belong, and where the carbon fiber and temperature claims are too.
Two omissions, both covered by cheaper products on this page.
No valve core removal tool: both Thinvik injectors include a CNC remover, and the core has to come out before any of these syringes can be used. The Park Tool omits it too.
No gauge: only the Park Tool TSI-1 has one.
What is not published
No hose length, where both Thinvik injectors publish 200 mm; no capacity in milliliters on the listing itself — 2 oz is 59 ml; no material beyond “durable materials that are easy to clean”; and no compatibility with other brands’ sealant.
The reference on the listing, AM-AC-059-parent, is the same code the 1 L sealant carries — a parent listing artefact rather than a part number, and a reminder to check which variant is in the basket.
