About Custom Seals
What Are Custom Seals?
Custom seals are specially designed sealing components manufactured to meet unique application requirements where standard sizes or materials are not suitable.
They are engineered based on specific operating conditions such as:
Pressure
Temperature
Media compatibility
Movement type (static, dynamic, rotary, reciprocating)
Installation structure
Custom Manufacturing Capabilities
We provide full engineering support for custom sealing solutions:
Non-standard sizes and geometries
Special cross-sections and sealing profiles (e.g., multi-lip, stepped, asymmetrical)
Material customization for chemical, oil, or high-temperature resistance
Precision manufacturing processes: molding, CNC machining, and stamping
Prototype development and small-batch testing
Every custom product is designed to ensure optimal sealing performance and long service life.
Materials Available
We offer a wide range of sealing materials for custom production:
NBR – General oil-resistant applications
FKM (Viton®) – High temperature and chemical resistance
EPDM – Water, steam, and outdoor environments
Silicone – Extreme temperature flexibility (–60°C to +230°C)
PTFE – Low friction and excellent chemical resistance
PU (Polyurethane) – High wear and pressure resistance
Material selection is based on your working conditions and performance requirements.

Frequently Asked Questions
What are custom seals?
Custom seals are specially engineered sealing components designed for non-standard applications where standard products cannot meet requirements.
Can you manufacture based on drawings or samples?
Yes, we can produce seals based on 2D/3D drawings, physical samples, or technical specifications.
What materials can be customized?
We support NBR, FKM, EPDM, Silicone, PTFE, PU, and other engineered compounds.
What is your minimum order quantity (MOQ)?
MOQ depends on product complexity. We support both small-batch prototyping and mass production.
How long does custom production take?
Lead time depends on design complexity and quantity. Typical timelines include sampling (5–15 days) and production (2–4 weeks), with expedited options available.
Do you provide engineering support?
Yes, we provide full technical support—from design optimization and material selection to performance validation.
