Tank Fitting Adapters
Tank Fitting Adapters
APT tank fitting adapters provide a high quality, cost-effective way to mount tank sumps to a standard 4" NPT tank opening or 6" NPT tank opening. The bright zinc plated cast iron construction is not only strong, but corrosion-resistant. The TFA-400-II and TFA-600 are easy to install and their single hole style mounting allows sumps to be rotated to properly align pipe entries.
- Easily installs with standard tools.
- TFA-400-II fits onto a standard 4" NPT tank riser pipe with 4" NPT internal threads for mounting a submersible pump.
- TFA-600 fits onto a standard 6" NPT tank riser pipe with 6" NPT internal threads for mounting a submersible pump.
- Installs through one hole in the sump base, permitting the sump to be rotated on the adapter to properly align pipe penetrations.
- Compression ring design allows installation with a solid gasket ring to ensure a watertight seal and environmental security.
