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.
Why choose custom-sized rubber products?
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%
Our core capability: Customization of size and shape
1. Unlimited size range
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)
2. Any shape can be manufactured
Basic shapes: O-rings, gaskets, seals, flat plates, irregular parts
Withstand high and low temperatures, physiological inertness
-60°C ~ +250°C
Food, medical, high-temperature environment
Chloroprene rubber (CR)
Weather-resistant, flame-retardant, medium oil-resistant
-40°C ~ +120°C
Outdoor equipment, fire protection requirements
Natural Rubber (NR)
High elasticity, wear-resistant
-50°C ~ +80°C
General machinery, vibration-damping components
Polyurethane Rubber (PU)
High intensity, high wear resistance
-30°C ~ +80°C
High-pressure, high-wear environment
Quality Assurance System
Dimensional Precision Control
Precision Measurement: Use of three-coordinate measuring machine, projector, and laser scanner
First Article Inspection: Comprehensive measurement of the first piece before each production batch
In-Process Sampling Inspection: Regular dimensional sampling inspection during production
