Performance and Application

T-type gland (for holes) DPT is commonly used in hydraulic reciprocating motion environments. Proper use excels in piston rod sealing applications under high, medium, and low pressure conditions, as well as heavy loads and high-frequency operations. The T-type gland is particularly suitable for long stroke applications and can accommodate larger piston rod clearances in a wide range of fluids and high-temperature environments. For example, it is widely used in equipment such as excavators, bulldozers, forging presses, ceramic brick presses, rolling mills, servo valves, and other machine tools. The unique R-section shape of this special T-type gland, with its side angle, allows for an additional degree of freedom, enabling the sealing element to slightly tilt. This allows the highest pressure point to be moved to the opposite side of the high-pressure side sealing edge, creating a middle deformation zone with no compression or shear load on the low-pressure side of the sealing element, thereby effectively reducing the risk of the seal being extruded.

Features:

Groove simple, suitable for integral piston.

2. Low friction, no creeping.

3. Excellent static sealing performance.

4. Due to the larger extrusion gap, it can be safely used in media with impurities.

5. Due to the versatility of the materials that can be used, it offers strong adaptability to working conditions.

6. Larger extrusion gaps are permissible, depending on the application, thereby reducing processing costs.

7. Suitable for new environmentally friendly and safe hydraulic fluids (bio-oils).
