"SSF" Design V-Packing
Heavy Duty,
Critical Service Packing

     "SSF" Design V-Packings incorporate twice the amount of material in their construction as the standard "SF" Design V-Packings. This extra material allows our "SSF" design sealing rings to resist rollover and distortion commonly seen in v-packings where excessive load and/or pressures are present. The result is a heavy duty, critical service packing that is able to withstand higher pressures and loads than other standard design packings.
     "SSF" Design V-Packing is recommended for use in large diameter applications where high pressure and loads are common, such as well servicing and hydraulic applications. This design is very effective in slurry applications when used with the Utex Header Ring. A wide variety of material compositions are available for most applications. Consult Fluid Sealing Service for more information on how this innovative design can help solve your sealing problems.

"ASF" Design Flat-Back Seal Ring
for use in all
Reciprocating, Centrifugal and Hydraulic Applications

     Utex Industries has significantly increased the sealing capabilities of Standard v-packings with the creation of our "ASF" Design Flat-Back Seal Ring. This design works extremely well in applications where high pressures are present. Although designed originally for reciprocating pumps, the "ASF" Design Flat-Back Seal Rings are now being used successfully in centrifugal and hydraulic applications.
     The secret to the success of this design is the amount of material used in each ring, combined with the engineered angles proven in high pressure situations. The extra material gives the "ASF" ring greater anti-extrusion ability plus over two (2) times the normal leakage path of a standard design v-ring. Another advantage of this design is the need for one adapter only. The flat top portion of the ring needs no special shaped adapter to make it fit a standard stuffing box, while also eliminating high stress caused by standard v-shaped adapters. The use of our "ASF" ring also allows you to use one sealing ring in place of multiple ring setups of the past. All of these features combine to make the "ASF" Design Flat-Back Seal Ring one of the most versatile packings on the market today.
     Available in many standard materials and can be supplied in a wide range of special compounds to work in your specific application. Consult Fluid Sealing Service for more information.

 Header Ring
for use where
Slurries And Other Large Particle Containing Fluids 
are being pumped

     The Utex Header Ring is designed primarily to be used with our "SSF" and "ASF" design v-rings where slurries and other large particle containing fluids are being pumped. The unique design of the Utex Header Ring keeps the product being pumped from working its way into the seal ring area and causing premature failure. At the same time, the Utex Header Ring acts as a spring to create a non-adjustable packing set. This adds greater service life to your packing and also cuts down on the maintenance time commonly associated with slurry pump applications.
     The Utex Header Ring is also available in three configurations for various applications. The most popular design wipes the outside diameter of a shaft or plunger. Another version is available for piston applications which wipes the inside diameter of a cylinder. A third version of the header ring is available with a flat top to be used with compression type packings.
     The Utex Header Ring comes in a wide variety of homogeneous compounds ranging from nitriles for general service, to flourocarbon elastomers for more severe applications. Special compounds are available upon request to meet your specific needs. To see how the Utex Header Ring can benefit you, call Fluid Sealing Service.

"KF" Design Hydraulic Ram Seals     Utex "KF" design seal has taken the place of ordinary hydraulic ram seals. Engineered

WF Design Short Stack Packing

     Utex WF Design Short Stack packing is designed to seal automatically in dynamic applications where stuffing box space is limited. The unique design does not require adapters that waste space in many other designs. Since no adapters are used, you can stock individual rings instead of sets which allows you more flexibility.
     The automatic sealing design of our WF rings means less gland pressure is necessary to actuate the seal. This allows the packing to run cooler and longer than other packing of similar design.
