Long Stem PU Foam Valve Customizable Extended Dispensing System with Vacuum Seal
Specialized valve for precise application of polyurethane foam in hard-to-reach areas during construction, manufacturing, and maintenance.
Product Overview
This long stem PU foam applicator features a two-component polyurethane foam system (including 1k pre-polymer and 2k systems) dispensed through an elongated, rigid plastic applicator stem. The extended reach enables targeted application deep into cavities, gaps, and voids inaccessible to standard nozzles.
Primary Applications
- Doors & Windows Installation: Delivers foam deep into rough openings around frames for complete insulation without surface overspray
- Cavity Wall Insulation: Fills deep voids in masonry and concrete blocks to enhance thermal and acoustic performance
- Pipe & Conduit Sealing: Creates fire, smoke, and air seals around wall/floor penetrations
- HVAC & Ductwork: Seals gaps around ducting in tight attic or crawl spaces
- Automotive/Marine Manufacturing: Provides precise application for sound dampening and insulation in vehicle cavities
- Appliance Insulation: Fills specific cavities during refrigerator, freezer, or water heater production/repair
Key Benefits
- Eliminates incomplete sealing in deep cavities
- Prevents messy overspray on finished surfaces
- Maximizes material efficiency with complete can emptying
- Accesses narrow, deep, or geometrically complex spaces
- Reduces labor inefficiency from makeshift solutions
