Full Metal Case: Provides superior structural integrity and stability, preventing deformation during installation and ensuring a perfect fit.

NBR Primary Lip: Offers exceptional resistance to fluid degradation and wear, maintaining its elasticity and sealing force across a wide temperature range.

Stainless Steel Spring: Consistently applies a uniform radial force, automatically compensating for lip wear to maintain optimal sealing pressure throughout the seal's entire service life.

Ideal For Use In:
Hydraulic Systems: Various hydraulic pumps, hydraulic motors, and rotary shaft applications.
Construction Machinery: Excavators, loaders, bulldozers, and cranes (travel motors, swing drives).
Agricultural Equipment: Tractors, combines, and other farm machinery transmission and hydraulic systems.
Industrial Applications: Gearboxes, drive shafts, and other industrial rotating equipment requiring oil retention.

FAQ

Q: Is this seal suitable for a high-pressure hydraulic pump on my excavator?
A: Absolutely. The DMHUI TCV seal is specifically engineered to perform in the high-pressure, high-speed environments typical of construction equipment hydraulic pumps and motors.

Q: Do you offer a quality guarantee on your products?
A: Yes. We are a factory-direct supplier, and all our products are manufactured under an ISO9001 certified quality management system, ensuring every unit you receive meets our high standards for performance and durability.

Q: How can I be sure this size will fit my application?
A: Please accurately measure your shaft diameter (must be 38.1mm), the housing bore diameter (must be 50.8mm), and the housing width (must be 6.35mm). All three dimensions must match for a proper seal. If you need assistance, our technical support team is here to help.
