What Diaphragm Direct does
Diaphragm Direct, a product brand of Sanitary Process Components (SPC), manufactures and distributes replacement diaphragms for sanitary diaphragm valves used in regulated process industries. Founded in 2017 and headquartered in Raleigh, North Carolina, the company's product portfolio centers on weir-style and radial-style replacement diaphragms, supplemented by sanitary gaskets and fasteners. Diaphragms are fabricated from FDA and USP Class VI compliant elastomer materials including peroxide-cured EPDM, PTFE-backed EPDM, FKM (Viton), platinum-cured silicone (VMQ), TFM/PTFE, and Butyl, with proprietary EPDM and PTFE formulations positioned to extend service life in frequent steam-cycle applications.
The company's technical differentiators include full batch traceability per EN10204 3.1b and ISO 10993-1, molded identification numbers on every diaphragm, independent validation testing through The Bioprocess Institute, and compliance with FDA, USP Class VI, 3A, ASME BPE (SG-3.1; SG-3.4), EMEA/410/01-TSE/BSE, and ISO 10993 standards. Diaphragm Direct maintains cross-reference compatibility with at least ten OEM valve platforms including Bürkert, Crane, Gemü, ITT, SED Flow Control, Georg Fischer, Swagelok/G.S. Anderson, Top Line, Bioengineering AG, and Watson-Marlow/Asepco, supported by a website featuring part number search, diaphragm questionnaire search, and manufacturer search.
Diaphragm Direct operates a quote-based, one-time-sale pricing model with no disclosed public pricing. Products are sold directly through a website RFQ system and distributed globally through a network of authorized distributors. The customer base spans four verticals — pharmaceutical, biotechnology, food & beverage (all marked as primary), and chemical processing — with applications including sterile fluid handling, CIP/SIP systems, aseptic processing, and sanitary flow control. The company is privately held with no disclosed parent, institutional investors, or funding history.

Diaphragm Direct competitors and assessment
Company assessmentDirect peers
- Trelleborg Sealing Solutions: Trelleborg is one of the largest global manufacturers of elastomer sealing components, including diaphragms and sanitary gaskets for process industries. Direct overlap with Diaphragm Direct in elastomeric replacement parts for sanitary valves, though Trelleborg serves a much broader portfolio beyond diaphragm valves.
- Freudenberg Sealing Technologies: Freudenberg produces high-performance elastomer sealing and diaphragm products for pharmaceutical, food & beverage, and chemical processing. Comparable in technical depth of elastomer formulations and in regulatory-grade documentation required for sanitary process applications.
- Garlock (EnPro Industries): Garlock is a specialist manufacturer of gaskets, seals, and packing for chemical, pharmaceutical, and food processing. Direct overlap with Diaphragm Direct's sanitary gasket offering and complementary presence in the same regulated process industry customers.
Broad incumbents
- Parker Hannifin (Seal Group): Parker is a diversified industrial components incumbent with a major elastomer seal and diaphragm product line serving process industries. It addresses the same sanitary process customer base but as part of a much broader motion, fluid handling, and sealing portfolio.
- Bürkert Werke: Bürkert is both an OEM Diaphragm Direct cross-references and a broader process automation incumbent selling diaphragm valves, controllers, and instrumentation into pharma and F&B. It is an OEM whose installed base Diaphragm Direct targets, and a competing supplier of original diaphragms.
- Gemü Valves: Gemü is a leading manufacturer of diaphragm valves and related actuators serving pharma, biotech, and F&B. It is both an OEM whose parts Diaphragm Direct replaces and a broad-incumbent competitor offering integrated valve-and-diaphragm solutions.
- Watson-Marlow (Spirax-Sarco): Watson-Marlow / Asepco is a process fluid handling incumbent whose radial diaphragm valves and Asepco line Diaphragm Direct targets with radial-style replacement parts. Direct interface point through aftermarket parts; broader incumbent in pumps, tubing, and bioprocessing components.
- Crane Process Flow Technologies: Crane manufactures diaphragm valves and process flow equipment for sanitary and industrial applications. It is one of the primary OEMs Diaphragm Direct cross-references (DA-series) and a broad-incumbent competitor for both valves and aftermarket parts.
- IDEX Corporation (ITT Engineered Valves): IDEX owns ITT Engineered Valves and other process fluid components, providing diaphragm valves and aftermarket diaphragms across pharma, biotech, and chemical markets. Broad incumbent competing both directly (via OEM diaphragms) and indirectly (via service programs).
Emerging players
- NewAge Industries (AdvantaPure): AdvantaPure is the pharmaceutical and biotech-focused division of NewAge Industries, specializing in sanitary tubing, single-use assemblies, and related sealing components. Comparable in serving regulated sanitary-process customers with elastomer-based consumables.
