App Concept

GapBridge Seal Kit

GapBridge is a patent-pending adapter system for HVAC, plumbing, and electrical installers that seals vertical gaps between misaligned drain pipes without cutting walls or lifting fixtures. It uses a telescoping rubber sleeve with compression rings to create a watertight seal in tight spaces, solving the 'no room for P-trap' and 'settled pipe gap' problems.

Key Features

Telescoping rubber sleeve with 1-2 inch adjustable length
Compression rings for tool-free watertight seal
Compatible with 1.5-2 inch PVC and brass pipes
3D-printed sizing guides for quick gap measurement

Target Users: Plumbers and HVAC installers working on residential drain repairs in tight crawlspaces or under showers

Revenue Model: SaaS subscription for access to digital gap measurement tool and sizing guides (freemium with basic kit purchase)
