TRUE FIT TANK FITTINGS INSTALLATION (See visual guide in image gallery)
- 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. Loctite 5331 is recommended.
- 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 attached in the image gallery.
- For Minimum Recommended Hole Sizes, kindly check the whole chart in the image gallery.
- Check the sealing surface to ensure it is free debris and/or scratches which could cause leakage.
- To obtain proper washer compression for fitting installation, ensure that the face of the washers are fully contacts to 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.
STEP-BY-STEP INSTALLATION PROCESS (See visual guide in image gallery)
- 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 manufacturers specifications.
4.) When adding additional fittings, it is recommended that either a thread sealing tape be used on all threaded connections. Loctite is recommended as a sealant.
