Flexible Tank Connections
Flexible tank connections help to alleviate the stress at fitting locations and increase the longevity of your tank by allowing the tank's sidewall to move freely.
The connections are available in both HDLPE and XLPE (same as the tank) for superior chemical resistance and lower cost when compared to traditional expansion joints. They are intended for use in low pressure piping applications only.

Flexible Tank Connections | CUSTOM FABRICATION |
Built from Tough Materials
We manufacture our flexible connectors using High-Density Linear Polyethylene (HDLPE) and Cross-linked Polyethylene (XLPE). These materials are strong, flexible, and built to handle a wide range of chemicals. So whether you’re pumping water, fertilizer, or industrial chemicals, these fittings can take it.
Low-Pressure Systems? This is Your Answer
Flexible tank connections are perfect for low-pressure systems. If your setup involves gravity feed, slow pumps, or basic flow control—these fittings are exactly what you need. They’re also a cost-effective replacement for larger, more expensive expansion joints.
Where Do Flexible Tank Connections Really Shine?
These connectors work across tons of applications. Here are a few real-world scenarios:
✅ Rainwater Harvesting Systems
Perfect for tanks that fill and drain frequently. These connections let the tank breathe and move without damaging your setup.
✅ Trailer-Mounted or Mobile Tanks
From fire-fighting trailers to de-icing systems, motion can wreak havoc on piping. These connections are made to move with your equipment.
✅ Agricultural Liquid Fertilizer Storage
Farm tanks are always in use. With constant filling and weather exposure, flexible connections make the whole system more reliable.
✅ Underground Installations
When soil shifts or ground settles, rigid pipes can crack. Flexible connectors help absorb movement underground.
✅ Temporary Tanks on Construction Sites
Moving tanks around? Set up is quicker and safer when the piping can handle motion. Flexible connectors save time and repairs.
✅ Tight Indoor Mechanical Rooms
Don’t have space to fight with your fittings? Flexible connections make those cramped installs easier and cleaner.
✅ Chemical Storage in Industrial Settings
Whether in car washes, food processing, or manufacturing, chemicals and pressure changes can wear out regular fittings. Our flexible connections hold strong.
Key material benefits:
-
Excellent chemical resistance
-
UV and weather resistant
