What All Seals Inc. does

All Seals Inc. is a full-line stocking distributor and custom manufacturer of industrial sealing products, founded in 1974 and headquartered in Lake Forest, California, with a second regional office in Pearland, Texas. The company supplies O-rings, mechanical seals, hydraulic seals, radial shaft seals, PTFE/Teflon products, sanitary gaskets, custom gaskets, EMI/RFI shielding components, custom molded rubber parts, rubber extrusions, cord and sheet stock, thread seals, lubricants, adhesives, plastic injection molded parts, braided packings, and precision machined metal components. Manufacturing capabilities span compression, transfer, and injection molding; elastomer compounding; CNC machining across 37 machines (including Tsugami Swiss machines, CNC turning centers, CNC lathes, and multi-spindle automatics); waterjet cutting; and precision quality inspection using 3D CMM, alloy spectrometer, tensile and hardness testers, and salt spray chambers.

The company serves OEMs and aftermarket customers across aerospace, food and dairy, pharmaceutical, medical (including implantable applications), automotive and powersports, oil and gas, mining, pool and spa, and general industrial equipment verticals. Its business model is primarily direct B2B sales via quote-based pricing, a toll-free contact line, and a request-a-quote workflow on its website, supplemented by value-added services including engineering design assistance, material compatibility analysis, friction management, vendor consolidation, kitting, sub-assembly, vendor managed inventory, global sourcing, and specialty packaging. Differentiated offerings include two proprietary friction-reduction treatments — Permaglyde® (a permanent PTFE-like coating) and PermaSlip® (an internal lubrication formulation) — both formulated for FDA and USP Class VI compliance.

The company holds AS9100D and ISO 9001:2015 certifications supporting aerospace and general industrial qualification, with additional compliance posture covering FDA CFR21, NSF/ANSI 51 and 61, USP Class VI, and Cyber Essentials. It operates as a privately held, founder/management-controlled business with no disclosed institutional investors, funding rounds, or M&A activity. Distribution partnerships with U.S. Seal Mfg., RT Dygert, DuPont (Viton®), and SIMRIT/Freudenberg (packings) extend its catalog of certified compounds and branded sealing lines, while its Hercules OEM-linked web presence suggests an emerging secondary brand targeting OEM contract work.
