Product Description

Product introduction

APPLICATION EXAMPLES

 Veepac seals are sets of fabric reinforced 
chevron rings. They are composed by a support 
ring, "V" shaped sealing rings and a pressure 
energizing ring.
 The support ring or base ring guides and sustains the other 
"V" shaped rings for best performance. Special versions 
provide incorporated anti-extrusion rings, either on the inner or 
outer side, for rod or piston applications (see type CH/NEI or 
CH/NEO). In standard version the support ring is manufactured 
in cotton fabric reinforced rubber, for a good anti-extrusion 
resistance.
 The intermediate "V" shaped rings (vee-rings) are the real 
sealing elements of Veepac seals. Their particular shape 
confirs the capacity of increasing sealing effectiveness under 
high pressure. In standard version they are made in cotton 
fabric reinforced NBR and pure NBR.
 The energizer ring ensures uniform loading of pressure on 
the other rings. This element is manufactured in acetal resin, 
or cotton fabric reinforced nitrile for diameters over 300 mm 
(standard material)
