Jaco P-P-4 Polypropylene 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. Polypropylene inserts eliminate the need for special high temperature inserts.

Specifications:

• Tubing Size: 1/4" OD
• Inner Diameter of Fitting: 1/8"
• Length of Fitting: 3/8"

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.
