Direct Answer

OEM Sealing Profiles Built Around Your Application

Onaseal supports B2B buyers, distributors and equipment manufacturers with drawing-based or sample-based profile development. The correct solution is selected from the mating geometry, operating gap, installation method, material exposure and order requirements—not from appearance alone.

For a dependable quotation, provide the cross-section, critical dimensions, material preference, color, required length, annual quantity and application photos. Trial samples should be fitted to the real assembly before mass production.

How to Specify Brush Seal Pile Height and Contact

InputWhat to measure or defineWhy it matters
Operating gapMinimum and maximum gap across the complete travel pathDefines the contact range the fibers must cover
Pile heightDistance from the top of the backing/base to the free fiber tipsMust provide continuous contact without excessive deflection
Working interferenceDifference between free pile height and the installed gapInfluences sealing contact, fiber bending and operating drag
Base or backingBase width/thickness, channel size or adhesive mounting widthControls retention and fit in the mounting feature
Pile constructionFiber material, density, fin option, color and required recoveryAffects light/dust control, stiffness, appearance and friction
MotionSliding direction, speed, cycle frequency and allowable forceDetermines whether contact produces acceptable resistance and wear
Direct answer: Select pile height from the entire gap range, not from one measurement. The fibers should maintain the required contact at the largest gap while avoiding excessive bend and drag at the smallest gap. Confirm the choice with a representative moving-assembly test.
Manufacturing Capability

What Onaseal Can Customize

Pile Height & Density

Review the working gap, intended interference, barrier function and allowable sliding force.

Base & Backing

Match base width and thickness to the channel, or define the adhesive footprint and substrate.

Brush Construction

Specify fiber color, density, fin option, recovery and environmental exposure requirements.

Roll & Packaging Format

Confirm reel or roll length, cut pieces, labels, carton quantity and export packaging.

Functional Validation

Brush Seal Sample Approval Checklist

CheckAcceptance questionRecommended test condition
Continuous contactDo fibers contact the mating surface through the full gap and travel range?Minimum/maximum gaps and actual corners or transitions
Operating forceDoes the door, window or mechanism move within the buyer's force limit?Complete moving assembly, not an isolated short sample
Recovery and wearDo fibers recover after cycling without unacceptable flattening or shedding?Buyer-defined cycle count and service direction
Dust, draft or light controlDoes the selected density and contact meet the required barrier function?Application-specific functional test
Mounting retentionDoes the base remain seated or bonded during motion and handling?Actual channel/substrate and installation method
EnvironmentAre moisture, temperature, UV and cleaning exposure acceptable?Declared service conditions and material review

A brush seal is a permeable contact barrier. It is commonly used for dust, drafts, light and debris control, but it should not be presented as a watertight substitute for a purpose-designed rubber or foam compression seal.

Four-Step OEM Cooperation

  1. Send a drawing, sample, photos and application requirements.
  2. Confirm section, material, dimensions, tolerances and commercial quantity.
  3. Approve tooling and trial samples after fit and performance checks.
  4. Proceed with batch production, inspection, packaging and export delivery.

Include these details for a useful quotation:

  • Minimum/maximum operating gap and travel path
  • Pile height, base width/thickness and mounting channel
  • Fiber density/fin/color and required barrier function
  • Sliding direction, cycle frequency and allowable operating force
  • Adhesive or channel mounting, roll length, quantity and packing
FAQ

Buyer Questions

Measure the minimum and maximum operating gap and maintain light continuous fiber contact without excessive drag.

Brush seals mainly control dust, drafts and debris. Water-tight applications typically require a rubber or foam seal.

Pile construction, color, base width, backing and packing can be discussed for OEM orders.
