Newborn 373-XSP Caulk Gun 10 oz
The Newborn 373-XSP is a revolving half-barrel caulk gun built for 10 oz cartridges. Its steel barrel and metal frame suit professionals and DIY users who apply sealants or adhesives regularly. A 26:1 thrust ratio delivers strong, consistent pressure for heavy materials. The rubber-coated grip and included ladder hook add convenience on the job.
Upgrading from lower-ratio or fixed-barrel guns
Moving from a standard 10:1 or ratchet-style gun to this 26:1 revolving model cuts the effort needed for stiff polyurethane, epoxy or high-viscosity sealants. The smooth-rod plunger and revolving barrel keep the cartridge aligned in corners and overhead work. The jump is worth it when daily volume or material thickness makes a basic gun tiring or slow.
Capacity and headroom for 10 oz cartridges
The gun accepts standard 10 oz cartridges and the high thrust handles thick formulas without stalling. It runs out of reach with larger sausage packs or bulk-loading systems that need a different barrel. The integrated seal puncture tool and ladder hook cover common site needs, but very large joints may still require multiple reloads.

Questions about this item
Will the 10 oz steel barrel fit my standard cartridge?
The half-barrel frame holds a 10 oz cartridge; the smooth rod plunger seats directly on the cartridge base.
How do I load the gun without the seal tool falling out?
Insert the cartridge, rotate the revolving barrel to align, then press the built-in seal puncture tool through the nozzle tip before dispensing.
What part wears first on the 26:1 thrust mechanism?
The smooth rod plunger and rubber-coated grip see the most friction; wipe excess sealant after each use to extend service life.
