TRUE FIT TANK FITTINGS INSTALLATION STEPS (See visual installation in image gallery or attached image)
- 1.) Remove the Back Nut and the Low Density Poly Washer (the firmer of the 2 washers) from the Tank Fitting Body. Slide the Tank Fitting Body through the hole in the tank. The rubber washer must be between the Fitting Body Flange and the tank wall (ensure the ribs on the Rubber Washer are sealing against the tank wall).
2.) On the inside of the tank wall, slide the Low Density Poly Washer back onto the Tank Fitting Body and then wind on the Back Nut.
3.) Tighten the Back Nut so that the face of both washers make full contact with the tank wall to obtain a water tight seal. Ensure that you comply with the tank manufacturer’s specifications.
4.) When adding additional fittings, it is recommended that either a thread sealing paste or thread sealing tape be used on all threaded connections. It is recommended to use LOCTITE 5331.
- Prior to installation, refer to tank manufacturer’s recommendations before drilling outlet in tank wall.
- All pipe work must be adequately supported.
- Use a thread sealant on all threaded connections. It is recommended to use Loctite 5331.
- If you are using chemicals or have any special requirements that you wish to use your Tank Fittings in,
check the Tank Fitting Chemical Resistance in the image gallery. - Please refer Minimum Recommended Hole Sizes listed below.
- Check the sealing surface to ensure it is free from debris and/or scratches which could cause leakage.
- To obtain proper washer compression for fitting installation ensure the face of the washers fully
contacts the tank wall. - Tighten the nut to ensure a water tight seal.
- HANSEN True Fit Tank Fitting can be used in conjunction with metal fittings.
