• 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 Threaded Pipe Fitting in, go to the Threaded Chemical resistance page or don't hesitate to contact us.
• Please refer to the dimensions tab for Minimum Recommended Hole Sizes
  

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.
