Fluoropolymer Coated Stud Bolts and Nuts,Fluorocarbon coated stud bolt& hex nuts

C&N offers high quality of ESPARRAGOS STUD BOLT A193 Grado  B7 w/2 NUTS A194 2H PTFE Xylan Coated Stud Bolts, ASTM A193 B7 PTFE Coated Stud bolt,fluorocarbon coated stud bolts

 Xylan coating because of its reputation in the Oil and Gas Industry as one of the premium coating providers for bolts and nuts. As a Qualified Approved Coater, our PTFE coated bolts and nuts have been used in various countries in South America,southeast Asia.Middle east.

Xylan coatings have a broad range of properties which make them ideal for a variety of applications. Xylan differs from traditional Fluoropolymer coatings in one very important aspect … they are composite materials. Lubricants with the lowest-known coefficient of friction are combined with the newest high temperature resistant organic polymers to create Xylan  coatings. Together these ingredients form “plastic alloys” with unique properties.

Among these properties are:
Low friction ( as low as 0.055)
Remarkable adhesion
Unusual resistance to wear and abrasion
Excellent resistance to corrosion
Resistance to chipping
Resistance to the elements: weather, sunlight, salt water
Working temperature range from: -190℃ to + 260 ℃
Available in a wide range of colors


Xylan 1424/ xylan 1070/ xylan 1014 FluoroCarbon coated stud bolts
Description: PTFE coated fasteners class coating Xylan 1424/ xylan 1070/ xylan 1014 has superb chemical and salt-spray resistance, It performs well in caustic environments, and comes in a wide range of colors. Xylan 1424 is ideal for offshore applications and in environments from sub-sea to splash zone to radio antennas. Xylan 1424 also reduces make-uptorque by as much as 70% and can be made up and broken out numerous times with little or no damage to the coating.
Main Properties: Low coefficient of friction. Abrasion /wear resistant. Dry film lubricant. Thermoset.. Corrosion resistant.
Typical Applications: Piston casing. Compressors. Threaded fasteners.
