Custom Rubber Seals & Strips
Your profile. Our production.
ETOL manufactures custom rubber seals and strips to fit your groove and assembly. Share your drawing so we can review the shape, material, color and hardness with you.
Start with a drawing, a sketch or a reference sample.
MADE TO YOUR DESIGNOEM / CUSTOM
01 / YOUR DESIGN COMES FIRST
A better fit starts with your cross-section.
From a continuous strip to a shaped sealing element, share the profile and mating surfaces. We review the design with you before making tooling and samples.
DESIGN CONCEPT
DESIGN CONCEPTU channels & edge trims
Match the opening, wall thickness and gripping section to your panel.
DESIGN CONCEPTCustom molded seals
Build special outlines, holes and locating features into your part.
These shapes are starting points. Send your own design for a manufacturing review.
DIMENSIONS · PROFILE · APPLICATION
Measure the profile. Define the installed gap.
A practical seal & strip brief, from first measurements to sample approval.
01 How to measure
- Supply a square-on end view with overall width (W), height (H), wall thickness (t), openings and lip or foot dimensions.
- Include cut length, length tolerance, corner details, joint locations and whether you need an open strip or a closed frame.
- Record the channel or panel size and the minimum and maximum closed gap. Measure the free profile without stretching or flattening it.
02 Cross-section library
Use these reference shapes to describe your requirement. Availability, tooling and dimensions are confirmed after drawing review.
03 Show where the seal fits
Show the mounting base or channel and the opposing surface. Include closed-gap variation, closure direction, corners and joints. For edge trims, provide panel thickness; for adhesive mounting, identify the substrate and finish.
Send an assembly section alongside the part drawing. Confirm free size, installed size and tolerances separately. Agree on compression and fit for the selected compound and geometry before approving a sample.
04 Choose a material with the application in view
Already specified a compound? Share its grade and datasheet. Otherwise, use this checklist to discuss silicone, EPDM, NBR, CR, FKM or another candidate with our team.
Contact media
List fluids, gases, cleaners and concentrations. Request compatibility review for the exact compound at the operating temperature.
Temperature & exposure
Separate continuous service from short peaks. Include outdoor exposure, immersion time and cleaning cycles.
Hardness & construction
State the hardness value and scale if known. For sponge or hollow profiles, include compression-force and recovery requirements.
Application requirements & appearance
Identify any contact requirements, test methods or traceability needs for the application. Specify color with a Pantone code.
A polymer name alone does not confirm temperature limits, chemical compatibility or compliance. Final selection depends on the compound, assembly and agreed validation conditions.
05 Confirm the operating conditions
Include the following with your drawing. Mark unknown items for review rather than guessing.
- Medium & temperature
- Contact medium, concentration, minimum / continuous / peak temperature and peak duration.
- Pressure & movement
- Working and peak differential pressure or vacuum; pressure direction; static or moving contact, speed, stroke and cycles.
- Assembly & environment
- Groove or panel dimensions, gap range, mating surfaces, closure or clamp force, cleaning and indoor / outdoor exposure.
- Acceptance & order
- Leakage or ingress target with test conditions, service-life target, drawing revision, quantity and requested delivery date.
Before production: agree on the drawing and compound, check sample dimensions and assembly fit, then evaluate sealing under the agreed conditions.

Custom manufacturing,
explained.
Can you make a profile that is not in your catalog?
Yes. Send a cross-section drawing, a sketch with dimensions or a reference sample. We will review the shape and agree on the tooling, material and sample requirements.
Can I specify adhesive backing or sponge rubber?
Include these requirements in your inquiry. We will review the construction, substrate and operating conditions before confirming the production specification.
What is the minimum order quantity, and how long will production take?
Minimum order quantity, tooling cost and sample and production timing depend on your design, material and quantity. Send your requirements so we can confirm these in your quote.
