High-Performance Entry Boots & Fittings
Engineered for absolute watertight integrity. Our flexible pipe entry seals protect your containment systems against groundwater ingress and environmental contamination.
Engineered For Extreme Environments
Our pipe entry boots are the result of precision elastomer engineering, ensuring that every penetration point in your containment system remains a fortress against leaks.
Advanced Elastomers
High-grade Nitrile (NBR) for fuel contact or EPDM for environmental sealing. Resistant to ozone, UV, and aggressive fuel additives.
Stainless Hardware
Standardized with 304 or 316 stainless steel compression rings to prevent corrosion in high-moisture sump environments.
Angular Flexibility
The bellows-style design allows for up to 15° of pipe misalignment, absorbing ground movement without compromising seal integrity.
Split-Style Ready
Available in split-style configurations for retrofitting existing pipelines without the need to dismantle the entire pipe run.

Nitrile (NBR) Compound
Best for: Direct fuel contact, petroleum vapors, and heavy chemical environments. High resistance to hydrocarbons and ethanol blends.
EPDM Compound
Best for: External environmental sealing, electrical conduit entry. Superior resistance to UV, ozone, and extreme temperature fluctuations.
Precision Fitting Guide
Follow our standardized installation protocol to ensure a 100% watertight seal between your containment walls and piping systems.
Drilling & Prep
Using a standard hole saw, create a precise opening based on our model size chart. Ensure the sump wall surface is smooth and free of burrs.
Compression Mount
Insert the boot body through the wall. Position the stainless steel compression rings on both sides and hand-tighten the bolt kits.
Pipe Insertion & Seal
Pass the pipe through the flexible bellows. Tighten the exterior stainless steel hose clamps to create the final liquid-tight seal.
Internal Compression Ring & Outer Bellows Assembly
