Bespoke elastomeric seals — molded, cut, bonded, and converted in-house.
From custom molded elastomeric profiles to die-cut gaskets turned around in 24–48 hours, PRP manufactures bespoke seals across the full range of elastomer conversion methods. Custom compound selection support included. If it can be specified, we can build it.
Every unique configuration. Under one roof.
Custom seal work at PRP spans four conversion methods — each available across the full elastomer compound portfolio with compound selection and geometry specification support from PRP’s application engineers.
Custom Molded Seals
Bespoke elastomeric profiles molded to print. Non-standard cross-sections, complex geometries, and application-specific configurations that standard catalog O-rings and seals won’t solve. Full compound range available — NBR, FKM, EPDM, VMQ, FFKM, and Parker EMG grades. Prototype seal fabrication available for qualification and development programs.
Die-Cut & Stamped Gaskets
Cut to print from sheet elastomer, PTFE, and composite materials. Standard and custom profiles. New die-cut shapes turned around in 24-48 hours — a lead time that matters when a maintenance window is open or a commissioning schedule is at risk. Laser cutting available for precision profiles and short-run configurations where hard tooling isn’t justified.
Elastomer Sheet Conversion
Custom sheet stock cut, slit, or converted to specification. PTFE sheet conversion for chemical resistance and high-purity fluid path applications. Composite material conversion available on application.
Rubber-to-Metal Bonded Assemblies
Elastomeric elements bonded to metal substrates in-house for integrated seal-and-structure applications. Custom configurations to print.
Lip Seals
Custom designed lip seals manufactured in-house and sourced through PRP’s specialty supplier network for dynamic sealing in rotating and reciprocating shaft applications. Custom configurations available to drawing.
The geometry is custom. The compound selection should be too.
Application-defined seal geometry specified against the wrong elastomer compound creates a failure mode that tooling can’t fix. PRP’s application engineering support covers compound selection for custom configurations across the full elastomer spectrum — media compatibility, temperature rating, regulatory compliance (USP Class VI, FDA, ISO 10993), and cleanliness requirements. Compound recommendation is part of the service, not an afterthought.
24-48 hours on die-cut. Custom molded on application.
Die-cut and stamped gaskets — new shapes turned around in 24–48 hours from approved drawing. Laser-cut profiles on similar timescales for qualifying runs. Custom molded seals — lead time on application, dependent on compound, geometry complexity, and tooling requirements. PRP’s ISO 9001:2015 quality management system governs all custom work — traceability and documentation included as standard.
VeriClean Seals™ — Custom Seals, Clean
Custom seal geometry and VeriClean surface cleanliness are not mutually exclusive. VeriClean
Seals™ processing is available for bespoke configurations — ISO Class 7 cleanroom processing and
documented particulate measurement and control from ≥1.3 µm applied to your custom seal before it
enters your system. No change to compound, durometer, dimensions, or chemical compatibility.
