Introduction
Sanitary processing lines in food, pharmaceutical, and cannabis extraction industries depend on precise inline filtration. A single compromised component like a screen gasket can cause contamination, production downtime, or regulatory failure — consequences that often trace back to poor component selection.
Tri clamp screen gaskets occupy a unique niche: they simultaneously seal and filter within a single sanitary fitting, making manufacturer selection critical for process integrity. This guide covers the top US-based tri clamp screen gasket manufacturers, what sets them apart, and the key factors buyers should evaluate — including material compliance, micron range, and lead times.
TLDR
- The right tri clamp screen gasket handles both sealing and inline filtration — one component, fewer fittings, cleaner process lines
- Top US manufacturers cover FDA/3-A compliant materials and mesh options from 10-micron fine filtration to 4-mesh coarse screening
- Key selection factors: material compliance (EPDM, silicone, PTFE), mesh spec, certifications (ISO9001, 3-A), and manufacturer support
- Dixon Sanitary offers the most documented standard product line with FDA-compliant materials and nationwide distribution
- For custom configurations or specialty filtration needs, Artesian Systems provides engineering-backed solutions with FDA 21CFR177.2600/1550 and 3-A compliant materials
Overview of Tri Clamp Screen Gaskets in US Sanitary Processing
A tri clamp screen gasket is a hybrid component combining a wire mesh filtration screen with a standard tri clamp gasket body. It installs between two sanitary ferrules secured by a tri clamp, enabling inline particulate filtration without requiring separate filter housings. This design protects downstream equipment — pumps, spray nozzles, valves, chromatography columns — from contamination while maintaining the sanitary connection standard.
Industries relying on these components include:
- Food and beverage processing
- Pharmaceutical and biotechnology manufacturing
- Nutraceuticals and dietary supplements
- Hemp and cannabis extraction
- Cosmetics and personal care
- Dairy processing
The US market imposes stringent compliance requirements across three primary frameworks:
- FDA 21 CFR 177.2600 — governs elastomer gasket bodies; limits aqueous extractives to 20 mg/sq in and restricts approved polymers
- FDA 21 CFR 177.1550 — applies to PTFE-bodied gaskets; caps total extractives at 3.1 mg/sq dm
- 3-A Sanitary Standards and USDA compliance — set material and design requirements for sanitary contact surfaces
With multiple manufacturers offering tri clamp screen gaskets in the US, buyers must evaluate beyond price alone. The suppliers listed below have been selected based on compliance credentials, material traceability, available size ranges, and demonstrated experience in regulated processing environments.

How We Chose the Best Tri Clamp Screen Gasket Manufacturers
The evaluation criteria used to identify top manufacturers included:
- Regulatory compliance — FDA 21CFR 177.2600 (elastomers) and 177.1550 (PTFE), 3-A Sanitary Standards, and USDA acceptance. As of January 2026, 3-A SSI introduced Replacement Parts Qualification Certification for seals and seal assemblies — a new verification pathway buyers should start requiring.
- Material quality and range — multiple elastomer options (EPDM, silicone, PTFE), mesh sizes from coarse (20–40 mesh) to fine (200–400 mesh or micron-rated), and 316L stainless steel for mesh screens.
- Certifications — ISO9001 quality management, USP Class VI testing for pharma applications, and documented material test reports with full traceability.
- Industry experience — proven experience in food, pharmaceutical, biotech, or extraction industries with a working understanding of sanitary process requirements.
- Custom engineering support — capacity for specialty mesh configurations, custom alloy machining, prototype system design, and application-specific engineering consultation.
A note on selection mistakes: Price is the most common filter buyers apply — and the most dangerous one in regulated industries. For pharma, food, and cannabis extraction operations, a manufacturer's ability to supply compliant material certificates, passivation services, and engineering-backed custom configurations matters more than brand recognition or distributor convenience.
Research identified that only Dixon Sanitary offers a fully documented standard screen gasket line with 18 SKUs across three materials. For buyers needing broader mesh options or deeper application engineering, that concentration makes specialized sanitary suppliers — not large diversified manufacturers — the more reliable source.
Conclusion
Choosing the right tri clamp screen gasket manufacturer in the US means evaluating material compliance, mesh precision, certification credentials, and whether the supplier can support custom process requirements alongside standard catalog offerings. Dixon Sanitary provides the most comprehensive documented standard product line with nationwide distribution, while companies like Artesian Systems deliver engineering-driven custom solutions for specialty applications.
Before finalizing your supplier selection:
- Request material compliance documentation (Certificates of Compliance referencing specific FDA CFR sections, Material Test Reports with traceability)
- Assess the manufacturer's experience in your specific industry and application
- Consider scalability and ongoing technical support as part of the supplier relationship
- Verify mesh specifications align with your particle size targets
- Confirm material temperature ranges match your process conditions
If your application calls for FDA 21CFR177.2600/1550 and 3-A compliant screen gaskets, custom inline filtration configurations, or engineering support for specialized process systems, Artesian Systems brings almost two decades of hands-on experience across food, pharmaceutical, and chemical industries — built on exactly the criteria outlined above.

Frequently Asked Questions
What is a tri clover gasket?
A tri clover (also called tri clamp or tri-clamp) gasket is a sanitary sealing component used between two sanitary ferrules secured by a tri clamp, designed to create a leak-proof, hygienic seal in food, pharma, and processing pipelines. "Tri-Clover" originated as a brand name owned by Alfa Laval but has become a generic industry term for this connection style.
What is a tri clamp screen gasket?
A tri clamp screen gasket integrates a wire mesh screen (typically 316L stainless steel) into a standard tri clamp gasket body, enabling inline filtration of particulates within a process line without requiring a separate filter housing. Available mesh sizes range from 10 micron through 4 mesh, with selection based on particle size targets and flow rate requirements.
What material makes the best gasket?
The right material depends on your process media, temperature range, and regulatory requirements. Silicone handles temperatures to 400°F with FDA compliance; EPDM excels in steam and CIP chemical environments (-60°F to 300°F); PTFE offers universal chemical inertness up to 200°F. For oil or petroleum derivatives, BUNA-N is a practical choice, while FKM/Viton handles aggressive chemicals up to 350°F.
Which gasket brand is best?
The right manufacturer depends on your application, compliance requirements, and whether standard or custom configurations are needed. Dixon Sanitary is a strong fit for high-volume standard needs with documented compliance and nationwide distribution. Artesian Systems suits custom, compliance-critical applications requiring engineering support, specialty alloys, or unique mesh configurations. Garlock works well where extreme chemical resistance with solid PTFE is the priority.
What mesh sizes are available for tri clamp screen gaskets?
Mesh sizes range from coarse (4 mesh / 4,760 microns) to very fine (10 micron rated). Common benchmarks include 20 mesh (~841 microns), 100 mesh (~149 microns), and 200 mesh (~74 microns). Artesian Systems offers 5, 20, and 100 micron options; Dixon Sanitary provides mesh specifications upon request.
Are tri clamp screen gaskets FDA compliant?
FDA compliance depends on the materials used. Compliant manufacturers source gasket bodies meeting FDA 21CFR177.2600 (elastomers) or 21CFR177.1550 (PTFE) with 316L stainless steel screens. Always request Certificates of Compliance, extraction test results, and USP Class VI documentation for pharmaceutical-grade verification.
