How To Request A Quote For Custom Seals
Direct Answer
To request a quote for custom seals, send drawings, dimensions, sample photos, material requirements, working media, pressure, temperature, movement type, equipment application, quantity, delivery target, and packaging needs. DEF Seals supports drawing-based customization, drawing creation support, sample-based customization, and small-batch sampling.
Why Custom Seal Quotes Need Technical Details
Custom seals cannot be quoted accurately by product name alone. The supplier needs enough information to confirm the seal profile, dimensions, material, production method, application risk, quantity, and delivery expectations.
Incomplete information can cause wrong material selection, wrong dimensions, unclear lead time, or repeated quotation revisions.
Custom Seal Quote Checklist
Drawing: 2D drawing, 3D drawing, groove drawing, or part drawing. This confirms profile and dimensions.
Dimensions: ID, OD, height, groove size, shaft or bore size. This reduces mismatch risk.
Sample photos: clear photos from multiple angles. This helps identify old or unknown seals.
Material: PTFE, filled PTFE, PU, NBR, FKM, UPE, PEEK, PET, or unknown. This supports material selection.
Working media: hydraulic oil, grease, water, fuel, chemicals, or air. This prevents incompatibility.
Temperature: operating temperature or environment. This helps avoid hardening or softening.
Pressure: normal and peak pressure if relevant. This helps evaluate extrusion risk.
Movement: static, reciprocating, rotary, or oscillating. This affects profile and material selection.
Equipment: hydraulic cylinder, pump, motor, or machinery type. This gives application context.
Quantity: sample quantity, trial order, or production volume. This affects quotation and planning.
Delivery target: required date or project schedule. This helps review feasibility.
Packaging: labels, bags, cartons, or export packing. This is important for procurement and logistics.
If You Have A Drawing
When a drawing is available, include all critical dimensions, tolerances, groove information, material requirements, application conditions, quantity, and delivery target.
DEF Seals supports drawing-based customization and can support drawing creation for custom projects.
If You Only Have A Sample
When only a physical sample is available, send clear photos, basic dimensions, equipment model, working media, temperature, pressure, movement type, and notes about the failure or replacement reason.
DEF Seals supports sample-based customization. Because old seals may be worn or deformed, buyers should still send measurements and working conditions.
If You Do Not Know The Material
Describe the working conditions first: the fluid or media touching the seal, temperature, pressure, movement type, environment, and old seal failure symptoms such as swelling, cracking, hardening, wear, or leakage.
The supplier can use this information to suggest a material direction, but final material selection should be confirmed before production.

FAQ
What is the fastest way to get a custom seal quote?
Send a complete drawing, dimensions, material requirement, working media, temperature, pressure, movement type, quantity, and delivery target. Photos and equipment details also help.
Can I request a quote without a drawing?
Yes. DEF Seals can start with sample photos, dimensions, and application details, and also supports drawing-based customization and drawing creation support.
What if I do not know the material?
Send media, temperature, pressure, movement type, equipment application, and failure symptoms. DEF Seals can review a suitable material direction based on the conditions.
Should I send the old seal size or groove size?
Send both if possible. Old seals may be worn or deformed, while groove and hardware dimensions help confirm the correct fit.
