True Fit Tank Fittings
  • Below is a general reference for the installation of all Hansen True Fit Threaded Pipe Fittings. The same installation principals apply for the Hansen True Fit Tank Plug such as the use of a threaded sealant.
  • All pipe work must be adequately supported.
  • Use a thread sealant on all threaded connections. We recommend Loctite 5331.
  • If you are using chemicals or have any special requirements that you wish to use your Tank Plug in, go to the Chemical resistance page or don't hesitate to contact us.


a) Use a thread paste sealant or (b) a teflon tape sealant. The right sealant for threaded joints is non-hardening, compatible with plastic and doesn't add slipperiness to encourage over-torquing.

Screw pipe into fitting.

Do not over tighten. The recommended way to assemble a Threaded Pipe Fitting is finger tight. Tighten until firm with spanner or pipe grip. One to two turns should be all that is required.
