What Inertech does
Inertech, Inc. is a privately held US manufacturer founded around 1990 and headquartered in Monterey Park, California, focused on expanded PTFE (ePTFE) sealing materials and specialty gaskets sold under the INERTEX brand. Its core technology is a proprietary isotropic expansion process for ePTFE, protected by US Patent No. 5,098,625, which produces a uniformly fibrillated microstructure with near-equal tensile strength in every direction and addresses the chronic creep and cold-flow weaknesses of conventional PTFE gaskets. The product portfolio spans form-in-place tapes (INERTEX UHF Gasket Tape and Joint Sealant), isotropic sheet and tape (SQ-S), low-torque solutions (EZ Seal, OPRA, LTC), and a metal-core high-pressure variant (Inermet with a corrugated 316 stainless steel core), serving operating envelopes from -450°F to +600°F, full vacuum to 3000 psi, and pH 0-14.
The company sells through a hybrid go-to-market: an extensive distributor network across the United States and Canada (18+ named Canadian distributors disclosed) handles volume distribution, while direct OEM sales and field engineering specialists support original equipment manufacturers worldwide in aerospace, chemical processing, oil and gas, pharmaceutical, food and beverage, power generation, semiconductor, marine, and other industrial verticals. Pricing is quote-based and consultative, with rapid response on both stock and engineered items, and a toll-free and direct-inquiry phone/email operation backs the channel.
Manufacturing runs out of AS9100D and ISO 9001:2015 certified facilities in Monterey Park. The product family is additionally certified to USP Plastic Class VI for pharmaceutical biocompatibility, NSF for food contact, ABS for marine (2019-2024 Type Approval), and UL for safety. Revenue mechanics are pure product sales of proprietary and specialty gaskets into regulated industrial applications, with no disclosed subscription, SaaS, or recurring-service component. Ownership appears to remain with founders or private insiders; no parent, subsidiary, or institutional investor is disclosed.

Products and services
- INERTEX UHF Gasket Tape Form-in-place 'Full Face Gasket on a Roll' ePTFE tape with pressure-sensitive adhesive and predetermined width for simple installation via seamless overlap even around bolt holes. Provides excellent creep relaxation and cold flow resistance for standard and nonstandard flange applications in industrial plants and OEM equipment.
- INERTEX UHF Joint Sealant Form-in-place 'Ring Gasket on a Roll' ePTFE sealant offering conformability and resistance to creep and cold flow for standard flanges, manways, tank covers, ducting, and heat exchangers. A widely used, versatile gasket material for industrial sealing applications.
- INERTEX SQ-S Isotropic Gasket Sheet 100% virgin expanded PTFE sheet produced using a proprietary Isotropic expansion process that provides nearly equal tensile strength in all directions, virtually eliminating creep and cold flow. Independently validated by Ecole Polytechnique Tightness Testing Research Laboratory (TTRL) as one of the tightest sealing PTFE sheet materials in the world. Available in standard sizes up to 80"x80" (including 60"x60" and 77"x77") with thicknesses from 0.5mm to 9mm. NSF certified (unbranded) for food-grade applications and USP Class VI certified for pharmaceutical use.
- INERTEX SQ-S Isotropic Gasket Tape Sheet gasket on a roll manufactured from Inertech's isotropic expanded PTFE process with self-adhesive backing. Provides the same isotropic sealing characteristics as SQ-S sheet material in a roll format, suited for large-diameter flanges, tongue-and-groove flanges, and glass-lined equipment.
- INERTEX EZ Seal Low-torque-to-seal gasket manufactured from SQ-S isotropic sheet material with a central precompressed area on the inside diameter and a narrow uncompressed sealing ring matching the raised face of an ANSI flange. Provides a robust leak-tight solution for applications requiring lower bolt load, such as fragile FRP and plastic flanges.
- INERTEX Inermet Specialty gasket with a corrugated 316 stainless steel core encapsulated between two 1/16" ePTFE facings. Concentrates gasket stress on the peaks of the insert while corrugations store compression energy to provide resiliency under cycling conditions. Improves high-temperature and high-pressure sealing performance.
- INERTEX Reduced Area Gaskets (OPRA, LTC, LTC-NR, OPRA/LTC Hybrid) Custom-engineered gaskets cut from SQ-S sheet material for the lowest allowable bolt loads, achieving ultra-low torque-to-seal performance. Includes OPRA (typically one-third area of a full-face gasket), LTC (two small strips of SQ-S material inboard of the bolt circle), LTC-NR, and OPRA/LTC HYBRID variants. Designed for fragile FRP and plastic flanges. Complies with FDA 21CFR177.1550.
