Grow1 Rubber Irrigation Grommets (25-Pack)

Professional Leak-Proof Sealing for Hydroponic Systems

Grow1 Rubber Grommets are a fundamental component for any DIY hydroponic builder or irrigation specialist. Engineered from high-quality, durable rubber, these grommets provide a watertight, airtight seal when plumbing tubing through the walls of reservoirs, buckets, or PVC pipes. They are designed to withstand constant exposure to nutrient solutions and UV light without cracking or degrading.

Versatile Plumbing Solutions

Whether you are building a Deep Water Culture (DWC) system, an Ebb and Flow setup, or a custom gravity-fed reservoir, these grommets ensure your bulkheads and tubing remain secure and leak-free. Their flexible construction allows for easy installation while maintaining enough rigidity to hold high-pressure seals over long periods.
