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.

Grade 8 nylon insert lock nut. The thread size is
2.25 in – 12 UNF and the nominal hex is
3.5 in.

Grade 8 lock nuts have a nylon insert in the nut that allows the nut to grab the fastener. This keeps the nut from backing off due to vibration.

This light duty wiper is molded in polyurethane and features a double-stepped shoulder to fit tightly in the gland throat.

Parback® backup ring with a curved cross-section.

Parbaks are contoured on one face to minimize distortion of the o-ring when under pressure. Parbaks should be installed with the contoured face against the o-ring, but reversal does no harm.

90A Durometer | Buna-N Rubber Material | 2 in Nominal Inner Diameter | 1/8 in Cross Section | Backup Ring

Features

• Excellent extrusion resistance
• Easily stretched for installation
• Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces
