Product Overview
The DuPont™ Tyvek® 400 Disposable Coverall with Hood, Elastic Cuff, White (TY127SWH) is a lightweight, single-use protective garment designed to provide dependable barrier protection against a wide range of workplace particulates and low-risk liquid splashes. Manufactured by DuPont, the original creator of Tyvek® fabric, this coverall combines strength, comfort, and breathable properties for extended wear in environments where contamination control and personal protection are essential.
Unlike reusable garment types, this coverall is disposable, minimizing risk of cross-contamination while eliminating laundering and maintenance. Its simple design — with a hood, elastic wrists and ankles, zipper front, and breathable fabric — makes it suitable for industrial, commercial, and laboratory tasks.
Key Material: DuPont™ Tyvek®
Tyvek® is a unique, proprietary material produced by DuPont using high-density polyethylene fibers. The structure resembles a spun-bonded, flash-spun network of fibers that creates a tough, durable, yet breathable barrier. Key characteristics of Tyvek® material include:
-
High tear resistance despite being lightweight
-
Breathability — helps reduce heat stress during wear
-
Barrier performance against non-hazardous dry particles and light liquid splashes
-
Low lint production — ideal for clean environments
-
Flexibility — doesn’t restrict movement
While Tyvek® fabric isn’t inherently chemical-resistant like heavy PVC or rubberized fabrics, its unique structure combines protection with comfort that many workwear fabrics cannot match.
Design Features of the TY127SWH Coverall
Fully Integrated Hood
The attached hood provides head and neck coverage, helping shield hair and scalp from particulate and light spray exposure. The hood design improves compatibility with other PPE — such as respirators, safety glasses, and face shields — by reducing exposed transition areas.
Elastic Cuffs and Ankles
Both wrists and ankles are equipped with elastic closures, which help maintain a snug fit and limit the entry of particles or contaminants. Elastic helps accommodate a range of body sizes while ensuring comfort and mobility.
Zipper Front Closure
The front zipper allows for quick donning and doffing with minimal hassle. A storm flap over the zipper helps maintain a continuous protective surface and can reduce snag points.
Breathability & Comfort
Thanks to the breathable nature of Tyvek® fabric, the coverall allows moisture vapor to escape while resisting penetration of particulates. This feature helps reduce heat stress, making it suitable for tasks requiring extended wear periods.
Lightweight, Disposable Construction
The coverall is designed as a single-use garment, eliminating the need for laundering, reducing contamination risks, and simplifying workflow in high-turnover environments.
Protective Performance
The TY127SWH coverall provides barrier protection suitable for a range of workplace exposures:
Particle Protection
The Tyvek® material offers reliable protection against non-hazardous dusts and fine particulates. This makes it useful for jobs where airborne particulate matter poses a contamination or safety concern — such as cleanup operations, abrasive blasting, and certain manufacturing tasks.
Light Splash Protection
The coverall offers limited liquid barrier performance against light splashes or low-pressure mist. It is not designed for high-risk chemical exposure or heavy liquid immersion. For these conditions, purpose-built chemical suits should be used.
Anti-Static Treatment (Optional)
Many DuPont™ Tyvek® garments, including some versions of the TY127SWH, undergo anti-static treatment to reduce static charge buildup. This is particularly relevant in environments where electrostatic discharge (ESD) could damage sensitive components or ignite flammable vapors.
Sizing & Fit
The TY127SWH coverall is available in multiple size options to accommodate a range of body types. Because it is made from a flexible and resilient material, the garment can conform to wearer movements while maintaining coverage.
Common sizes might include:
-
Small (S)
-
Medium (M)
-
Large (L)
-
Extra Large (XL)
-
Double Extra Large (XXL)
Fit considerations:
-
The elastic wrists and ankles help reduce gaps without restricting range of motion.
-
Some workers may size up if they need to wear insulating clothing beneath the coverall in cold conditions.
-
Always refer to DuPont’s sizing chart for accurate selection and to ensure sufficient overlap with gloves, boots, and other PPE.
Typical Use Cases & Industries
The versatility of the Tyvek® 400 coverall makes it useful across many environments where particle control, cleanliness, and general protection are priorities:
Industrial Maintenance & Manufacturing
-
Sanding, grinding, and metalworking cleanup
-
Painting preparation (overspray protection)
-
General maintenance tasks
Construction & Renovation
-
Drywall sanding and debris cleanup
-
Insulation work where dust exposure is present
Laboratory & Cleanroom Support
-
Lab support tasks not requiring full chemical resistance
-
Clean areas where lint reduction is important
Facilities Cleaning & Janitorial Work
-
Contamination control during cleaning operations
-
Minimizing transfer of particulates
Standards & Certifications
The TY127SWH coverall typically meets several protective garment performance standards — depending on the specific variant and certification labeling:
-
EN 13982-1 (Type 5) — Protection against hazardous dry particulates
-
EN 13034 (Type 6) — Limited splash protection
-
ASTM D6978 (if applicable) — Chemotherapy drug protection (some versions)
-
Anti-static properties where treated
Always verify garment labels or product documentation for specific test ratings and performance claims relevant to your jurisdiction.
Care, Use & Disposal
Proper Donning & Doffing
To maximize protective performance:
-
Ensure wrists and ankles are snug.
-
Fasten the zipper completely.
-
Wear compatible gloves and boots that overlap with elastic cuffs.
-
Remove carefully to avoid contamination spread.
Single-Use Disposal
Because it is designed as disposable PPE, do not attempt to wash or reuse — especially after exposure to contaminants. Dispose of used garments following workplace biosafety, environmental, and industrial waste protocols.
Storage
Store coveralls in a clean, dry area away from direct sunlight, extreme temperatures, and chemicals. This preserves material integrity until use.
Limitations
While effective for many tasks, the Tyvek® 400 coverall is not suitable for:
-
Protection against large volumes of liquid under pressure
-
Strong corrosive chemicals or hazardous substances
-
Fire-resistant or arc flash applications
-
Environments requiring full encapsulation suits
In such cases, specialized protective suits (e.g., chemical-resistant, flame-retardant garments) are required.
