SL127T Hooded Chemical Coveralls with Taped Seams
DuPont Tychem 4000 SL127T is a white, limited-use chemical protective coverall with a standard-fit hood, elastic wrists and ankles, taped seams, and a front zipper under an adhesive storm flap. This ASA listing is one case of six coveralls in your selected size: L, XL, 2X or 3X.
Tychem 4000 uses a chemical-barrier film laminated to a Tyvek substrate. DuPont reports that the fabric provides at least 30 minutes of protection against more than 124 chemical challenges under specified test conditions. Those fabric results do not guarantee whole-garment protection, suitability for every chemical, or a safe wear time.

Verify the Chemical and Complete PPE Ensemble
Chemical protection is hazard-specific. Before use, verify the exact chemical, concentration, temperature, physical state, exposure duration, permeation data, seam and closure performance, and all respiratory, hand, eye, face and foot protection required by the hazard assessment. Review the current DuPont SL127T technical data sheet and DuPont SafeSPEC.

ASTM Test and Garment Limitations
DuPont reports that Tychem 4000 fabric passes ASTM F1670 synthetic-blood and ASTM F1671 viral-penetration test methods. These fabric tests do not establish universal biological protection or make the garment a Level A, B or C ensemble by itself. SL127T is not flame-resistant or arc-rated and should not be used around heat, flames, sparks, electric arc exposure, or potentially flammable or explosive atmospheres.
Limited-Use Garment
Do not return a contaminated, damaged, altered, torn, abraded or punctured garment to service. DuPont does not recommend washing contaminated Tychem garments for reuse. Follow the current DuPont user instructions and the employer's inspection, removal, decontamination and disposal procedures.
DuPont Tychem 4000 SL127T FAQ
What is included in the Tychem 4000 SL127T configuration?
SL127T is a white Tychem 4000 coverall with a standard-fit hood, elastic wrists and ankles, taped seams, a pin-lock zipper pull, and an adhesive storm flap over the zipper. It does not include attached socks or protective outer boots.
How is this DuPont Tychem 4000 coverall sold?
This ASA listing is sold as a case of six coveralls in one selected size. The current ASA size choices are L, XL, 2X and 3X.
Which chemicals is SL127T suitable for?
Suitability depends on the exact chemical, concentration, temperature, physical state, exposure duration and complete garment configuration. Review the current DuPont permeation data and SafeSPEC guidance; fabric test results do not guarantee whole-garment protection or a safe wear time.
What do ASTM F1670 and ASTM F1671 mean for this coverall?
DuPont reports that Tychem 4000 fabric passes ASTM F1670 synthetic-blood and ASTM F1671 viral-penetration test methods. These are defined test results, not a guarantee of protection against every biological hazard or exposure condition.
Is SL127T a Level A, B or C hazmat suit?
No garment receives an ensemble level by itself. SL127T is a non-encapsulating coverall. The employer's hazard assessment, respiratory protection and complete PPE system determine whether an ensemble meets the requirements of a specific response level.
What is the difference between SL127T and ASA's SL122B coverall?
SL127T uses taped seams, elastic wrists and elastic ankles and is sold by ASA as a six-coverall case. ASA's SL122B listing uses bound seams, elastic wrists and attached garment socks and is sold as one suit. Confirm the exact style before ordering.
Can Tychem 4000 coveralls be washed and reused?
Tychem 4000 garments are designed for limited use. DuPont does not recommend washing contaminated garments for reuse. Remove a garment from service if it is contaminated, damaged, altered, torn, abraded or punctured.
Is Tychem 4000 flame-resistant or arc-rated?
No. SL127T is not flame-resistant or arc-rated. Do not use it around heat, flames, sparks, electric arc exposure, or potentially flammable or explosive atmospheres.
