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. 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. 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.

Cast Iron Rod Clevis Mount with a 1 in – 14 TPI threaded end and a 1 in pin hole.
Clevis mounts help maintain alignment and protect the cylinder from side load. Mounts attach to threaded stud ends, pivot holes, or bolt holes on the cylinder. Can be used with hydraulic cylinders with standard bore sizes.
O-rings as elastic loops that seal static and dynamic applications. They are used to seal the space between cylinders, pistons, pipes and tubes and can be made from various materials.

This U-cup style buffer ring offers an asymmetric sealing lip profile, chamfered sealing edges, and pressure relieving capabilities to prevent inner pressure entrapment when employed in a tandem sealing system. This rod buffer seal is designed to absorb impact pressure fluctuations under high-load conditions thus increasing the life of the primary seal.

HC-5625-12 has a 6.5 in OD and is made to fit a 5 in bore cylinder.
Head cap size is determined based on the bending stress.
A static seal or o-ring is used in between the head cap and barrel (except welded construction).
The main function of the head cap is to enclose the pressure chamber at one end. The cap is connected to the cylinder body by means of welding, threading, bolts, or tie rod.
