IWS Gland — Compression Sealing Gland for Pipe-to-Tank Connections

IWS Gland — Compression Sealing Gland for Watertight Pipe-to-Tank Connections

Create a watertight connection between your pipe and tank (or any hard surface) with an IWS Sealing Gland — the same one used in IWS Systems. You won't get any leaks. Pipes are sealed in with a compression fitting. Simply feed your pipe into the gland, attach it to your tank (2 washers and 1 nut included). As you screw everything together, the pipe is sealed.

Why growers need IWS Glands:

• Watertight pipe-to-tank seal — no leaks at the critical connection point
• Compression fitting design — proper engineering, not just rubber rings
• Used in genuine IWS Systems — proven in years of grow-room service
• 2 washers and 1 nut included — complete fitting, no extras needed
• Easy installation — feed pipe, attach, screw to seal
• Compatible with hard-surface tanks — works with rigid plastic or steel reservoirs
• Essential for any IWS or custom hydroponic build — every tank needs sealed exit points

Who it's not for:

Check the pipe diameter — IWS Glands come in different sizes for 13mm, 25mm, etc. Wrong size won't seal properly. For flexible-walled containers (rather than rigid), the compression fit may not work — use a different sealing approach. For very high-pressure applications, check the gland's pressure rating. Pair with the rest of the IWS system or use as a standalone fitting in custom hydroponic builds.
