Bound-Seam Chemical Coverall with Hood and Attached Socks
The DuPont Tychem 4000 SL122B is a white, 12-mil limited-use chemical protective coverall with a standard-fit hood, elastic wrists, attached socks, bound seams, and a front zipper under an adhesive storm flap. ASA sells this listing as one suit each in sizes M through 4X; DuPont's manufacturer case quantity is 12 suits.
Tychem 4000 uses a chemical-barrier film laminated to a Tyvek substrate. DuPont reports fabric testing against more than 120 chemical challenges under specified laboratory conditions. Those results describe the fabric, not guaranteed whole-garment protection or safe wear time. Seams and closures may have shorter breakthrough times and higher permeation rates.

DuPont Tychem 4000 SL122B FAQ
What is included in the SL122B garment configuration?
SL122B is a white Tychem 4000 coverall with a standard-fit hood, elastic wrists, attached socks, bound seams, a pin-lock zipper pull, and an adhesive storm flap over the zipper.
Which chemicals is SL122B suitable for?
Suitability is hazard-specific. Review DuPont SafeSPEC for the exact chemical, concentration, temperature, physical state, exposure duration, seam construction, and garment configuration. Fabric test results do not guarantee whole-garment protection or safe wear time.
When should a taped-seam garment be considered instead?
Select seam construction through a documented hazard assessment. DuPont warns that some hazardous liquids, including strong acids, can degrade serged and bound seams; this bound-seam style should not be worn when those chemicals are present.
Are the attached socks protective boots?
No. The garment-material socks must be worn inside separately selected protective outer footwear. They are not durable or slip-resistant enough to serve as the outer foot covering.
Does Tychem 4000 meet ASTM F1670 and ASTM F1671?
DuPont reports that Tychem 4000 fabric passes the ASTM F1670 synthetic-blood and ASTM F1671 viral-penetration test methods. These fabric results do not establish universal biological protection for every garment configuration or exposure.
Is SL122B a Level A, B, or C hazmat suit?
No garment receives an ensemble level by itself. SL122B is a non-encapsulating coverall; the employer's hazard assessment, respiratory protection, and complete PPE system determine any Level A, B, or C ensemble use.
Can Tychem 4000 garments be washed and reused?
Tychem 4000 garments are designed for limited use. Do not return a contaminated, damaged, altered, torn, abraded, or punctured garment to service. Follow the current DuPont user manual and workplace disposal procedures.
Is this listing for one suit or a full case?
This ASA listing is sold as one suit each. DuPont's manufacturer case quantity for SL122B is 12 suits.
