<strong>ISOLATING</strong> SLEEVES & WASHERS • <strong>FLANGE</strong> PROTECTORS<br />

<strong>ISOLATING</strong> SLEEVES<br />

AND WASHERS<br />

Isolating sleeves manufactured of<br />

high density polyethylene, NEMA<br />

grade LE phenolic, and Mylar are<br />

available in a full range of sizes. Also<br />

available are one-piece integral<br />

sleeves and washers which are made<br />

of Minlon, providing superior<br />

compression strength. Integral<br />

sleeves are available in sizes up to<br />

1-1/2”. A variety of high temperature<br />

sleeves are also stock items.<br />

With each insulating washer a 1/8”<br />

thick S.A.E. electro-plated steel<br />

washer is provided to protect the<br />

isolating washer from damage by the<br />

nut. Advance flange isolation sets are<br />

available in single or double washer<br />

kits.<br />

KLEERBAND ® <strong>FLANGE</strong><br />

PROTECTORS<br />

Kleerband ® and Stainless Steel<br />

Flange Protectors and Radolid ®<br />

Protection Caps are two additional<br />

ways to further seal flanges from<br />

corrosion.<br />

Flange protectors and corrosion<br />

inhibitor grease are recommended on<br />

all isolated flanges. By<br />

encapsulating the flange cavity with<br />

the flange protector and injecting our<br />

corrosion inhibitor grease, you can<br />

rely on your cathodic protection<br />

system to provide you with years of<br />

trouble free service.<br />

This system totally eliminates any<br />

possibility of foreign material lodging<br />

between the faces of your flange or<br />

corrosion bridging across and<br />

creating a short.<br />

RADOLID ® PROTECTION<br />

CAPS WITH VCI*<br />

Radolid ® Protection Caps from<br />

APS protect nuts and bolts from<br />

destructive corrosion. Caps are<br />

easily pressed onto the bolted<br />

joints by hand, snapping into<br />

place when in position. We<br />

recommend loading caps with<br />

APS’s high-melt corrosion inhibitor<br />

grease for added protection.<br />
