High Pressure Compression Fittings
The Spectra-Pearson Pump is equipped with compression fittings for reliability and
easier service. These fittings are used to connect the raw water outlet on the plumbing
manifold to the raw water inlet on the Spectra-Pearson Pump. Should these fittings need
to be replaced or repaired, follow the instructions below to ensure leak-free service.
Use
ONLY
Dayco Imperial Nylo-Seal 88-NSR-1/2 tubing for high pressure connections.
Carefully fit and measure the tubing before cutting with a sharp razor knife or hose cutter and remove
any burrs. Minimum tubing bend radius is 6”. Route tubing away from excessive heat sources and
secure from vibration and chafe. Have at least one shallow bend in a tube assembly after it is installed.
Refer to figure 1.
If a fitting has been dissembled, reassemble as illustrated. The notch on the ferrule
must engage the inside of the nut properly for the nut to seat down fully. Once the tube is inserted the
ferrule and nut will naturally align.
Refer to figure 2.
Insert tube fully into the fitting, it should go in 0.9”. Tighten the nut finger tight while
moving the tube around to prevent binding. One thread should be showing under the nut. Secure the tube
so it won’t back out when tightening.
Refer to figure 3.
Use 13/16” wrench to hold a straight body fitting or a 3/4” wrench for a 90º body, and
a 7/8” wrench for the nut. Hold the body, recheck the tube insertion, then tighten the nut 1-1/4 turns. Use
the index mark on the nut as a guide. The threads should be completely covered by the nut.
Make Sure these fittings are tight on initial assembly or they will fail!
