Industrial Mechanical Seals | Custom Dimensions & Shapes | Made to Your Exact Specifications

We specialize in rubber products manufactured precisely according to drawings—with no minimum size restrictions and no constraints on standard shapes, providing your equipment with perfectly matched sealing solutions.

Precise matching ensures perfect sealing.

Standard-sized rubber parts often cannot fit your equipment perfectly, leading to leaks, wear, or reduced efficiency. Our fully customized service ensures that every rubber component can:

• Fit the equipment interface perfectly, eliminating the risk of leaks
• Precisely meet the requirements for mechanical motion clearances
• Optimize material selection for specific media (oil, water, chemicals)
• Adapt to extreme temperature and pressure operating conditions
• Extend the overall service life of the equipment by more than 30%

• Thickness: 0.2mm to 100mm
• Diameter/Inner diameter: 1mm to 2000mm
• Length/Width: Unlimited, cut to order
• Tolerance control: ±0.1mm to ±0.5mm (as per application requirements)

• Basic shapes: O-rings, gaskets, seals, flat plates, irregular parts
• Complex profiles: Gear-shaped, maze-like, multi-layer composite structures
• Cross-sectional shapes: Rectangular, circular, D-shaped, X-shaped, U-shaped, V-shaped, and irregular cross-sections
• Special requirements: With mounting grooves, metal inserts, adhesive backing, perforated design

• Production according to drawings: Provide drawings in formats such as CAD, PDF, DWG
• Replication according to samples: Send samples, and we will accurately measure and replicate them
• Collaborative design: Describe the application scenario, and our engineers will design the optimal solution for you
