Holdrite HF-CG-20SP Hydroflame Caulk Gun 20 Ounce

Product Description

The HOLDRITE HF-CG-20SP is a full-size dripless caulk gun designed to dispense firestop sealants, grout, and standard-viscosity adhesives in residential and commercial construction applications. Built around a rotating swivel barrel and double-gripping plate technology, the HF-CG-20SP reduces hand fatigue and prevents slipping during continuous application. The anti-drip nozzle stops material waste between beads, and the heavy-duty sausage pistons resist bag-wrap when working with foil-pack firestop materials. Plumbers, firestop contractors, and construction tradespeople will find this tool suited to penetration sealing and joint applications where controlled, mess-free dispensing matters.

The HF-CG-20SP is sized for 20-ounce tubes and is part of the HoldRite HydroFlame firestop product line, making it a natural pairing with HydroFlame caulk and sealant products. Typical use cases include sealing pipe penetrations through fire-rated walls and floors, applying firestop sealant around bathtub and shower surrounds, and dispensing adhesives in tight or overhead spaces where barrel rotation and grip stability reduce applicator error. The tool is suited for both residential new construction and commercial retrofit firestop work.

Installation Notes

Firestop penetration sealing is typically performed by licensed plumbers or certified firestop contractors in accordance with applicable building and fire codes. Before applying firestop sealant to penetrations, confirm the opening is clean, dry, and free of debris. Follow the sealant manufacturer instructions for minimum bead size and cure time. Never apply firestop products over uncured or incompatible joint materials.
