Jaco N-P-4 Nylon Tube Insert Fittings are used in soft or thin wall tubing. The inserts will not wear a hole in the tubing, and provide a grip to prevent sliding due to heat expansion. Nylon inserts eliminate the need for special high temperature inserts.

Advantages of JACO fittings over metal compression fittings:
  • Good electrical insulating qualities. This eliminates the electrolytic action that corrodes tubing, caused by a dissimilar metal meeting a fitting.
  • Low density and softness of plastic gives JACO fittings the ability to absorb mechanical and acoustical vibrations.
  • Low resistance to flow due to the smooth internal surface of the fittings.
  • Resistance to scale buildup.
Specifications:
  • Tubing Size: 1/4" OD
  • Inside Diameter of Fitting: 1/8"
  • Length Of Fitting: 3/8"
