The Z-Seal™ is a squeeze type seal, combining the excellent sealability and low compression set of a resilient rubber lip with the greater anti-extrusion characteristics of a hard thermoplastic base. Under low pressure conditions, the sealing lip provides its own compressive seal force. As pressure increases, hydrostatic pressure is mechanically transmitted through the elastomeric seal element into the anti-extrusion base. The applied force then deflects radially in a controlled manner, closing the extrusion gap behind the sealing lip. Under this condition, maximum sealing effectiveness is achieved.

US-90URE-9×9-3/4×5/8

Top-of-the-range twin lip rod seal designed to provide a dry sealing solution in heavy-duty applications. The seal’s shell is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance. Featuring high pressure and high shock load capability, this seal utilizes the same twin lip design found in Hercules®, Sealing Products’ RTU style. With the main body of the seal molded from high performance polyurethane, this seal, incorporates a dynamically designed nitrile energizer and a tough polyacetal anti-extrusion ring. RTUB is capable of, pressures up to 10,000 psi in approved applications.

Features

• General purpose rod seal
• Robust design
• Excellent wear resistance
• Increase seal stability
• Performs well over wide temperature range and is extremely effective in low temperatures
• Primary lip protection
• Easy to install

Molded from 93 Shore A polyurethane with a 70 Shore A energizer, this seal utilizes the same groove dimensions as a standard o-ring or T-seal. One or two Style 575 back-up rings may be used for wider grooves. Extrusion resistant by design, this seal is also resistant to rolling and twisting. Installation is an easy two step snap-in procedure with no need to re-size before insertion into the bore. Piston diameter “I” dimensions are given for pistons without wear rings.

Utilizing the same profiles as the Style 800 Polyurethane U-Seal line, these u-seals are molded from a fluorocarbon, compound. While being compatible with a broader range of fluids, these fluorocarbon seals will also operate, continuously at temperatures from -20° to +400 °F. NOTE: If you are not sure of fluid/seal compatibility, please refer, to the fluid compatibility chart in the appendix or contact our Engineering Department.

TR-750 has a 0.75 in diameter. The material is 1144 Carbon Steel, which is equivalent to Stressproof tie rod.

Tie rods are sold in 12 ft. lengths only. Rods can be cut for UPS shipment or left whole, if necessary. Freight charges may vary depending on required length.

Full mill lengths will be cut to lengths between 12 ft and 19 ft long. Packages longer than 44 inches may have additional freight charges.

The twin lip design helps solve difficult rod sealing problems by providing lower friction, increased stability, and high, dynamic lip force, while preventing air penetration from outside the cylinder.

Asymmetric rod seal designed with precision trimmed sealing lips to provide a dry sealing solution in light and medium-duty applications. The Hallite 605 is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.

Designed to have interference in the seal housing groove and has a secondary lip. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The inner dynamic lip is shorter and more robust to improve sealing and compression set characteristics over conventional, symmetrical U-seals. The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are precision trimmed at an angle to give optimal rod sealing performance.
