What Materials Do We Use for Our NEMA 6 / IP67 Enclosures?
SLAYSON® selects materials based on the chemical and physical demands of your specific environment. Our NEMA 6 / IP67 range is primarily manufactured in two high-performance alloys:
Stainless Steel
Type 316 stainless steel is commonly specified for NEMA 6 / IP67 enclosures where corrosion resistance and long-term durability are critical. The alloy’s high chromium and nickel content provides strong resistance to moisture, chemicals, and salt-laden environments.
SLAYSON® stainless steel NEMA 6 / IP67 enclosures are supplied with a polished finish as standard. Alternative surface finishes, including blasted or non-reflective options, are available to suit installation and environmental requirements.
Aluminium
Select NEMA 6 / IP67 enclosures are manufactured from aluminum alloys such as 5052 and 6061. These materials offer a favorable strength-to-weight ratio and are well-suited to applications where weight reduction or ease of installation are priorities.
To meet ingress protection and corrosion resistance requirements, SLAYSON® aluminum NEMA 6 / IP67 enclosures are supplied with protective surface coatings. Available coating options improve resistance to moisture and environmental exposure in outdoor and washdown conditions.
UL
UL certification is a safety standard issued by Underwriters Laboratories (UL) to verify that products meet rigorous electrical, mechanical, and fire protection requirements. UL-certified enclosures undergo strict testing to ensure compliance with industry regulations, enhancing reliability and safety in industrial, commercial, and hazardous environments where regulatory approval is essential.
NEMA 6
NEMA 6 is a National Electrical Manufacturers Association (NEMA) enclosure rating that defines protection against dust ingress and powerful water exposure, including temporary submersion.
Though not rated for prolonged immersion like NEMA 6P, it provides robust sealing and reliability in demanding environments. It remains ideal for industrial, outdoor, and washdown applications where short-term submersion or heavy water exposure is a concern.
IP67
IP67 is an Ingress Protection rating defined under IEC 60529. It indicates complete protection against dust ingress and temporary water submersion under controlled conditions.
A “6” in the IP rating indicates complete protection against dust ingress, while a “7” denotes resistance to short-term water immersion, typically up to one meter. IP67 enclosures are therefore applied in outdoor, washdown, and other wet environments where brief submersion is possible.
IK10
IK10 is the highest impact protection rating under the IEC 62262 standard, indicating an enclosure can withstand 20 joules of impact energy. This equates to a 5kg object dropped from 400mm. IK10-rated enclosures provide maximum resistance against mechanical impacts, making them ideal for industrial and public-facing installations where physical damage is a concern.
EMC
Electromagnetic compatibility (EMC) protection addresses the control of electromagnetic interference (EMI) and radio frequency interference (RFI).
EMC-capable enclosures incorporate conductive materials, gaskets, and surface treatments to limit signal leakage and external interference. These features support compliance requirements and help protect sensitive electronic equipment in electrically noisy environments.
NEMA 6 / IP67 Industry Use Cases: Engineered for Reliability
SLAYSON® NEMA 6 / IP67 enclosures are used across industries where dust ingress, washdown exposure, and temporary flooding must be managed without specifying deep-water submersion protection.
Common application environments include the following.
- Infrastructure & Tunnels: In tunnel infrastructure, refurbishment, and maintenance projects, equipment is routinely exposed to heavy washdown procedures and groundwater ingress. SLAYSON® provides the standard for enclosures used in these environments, protecting vital signaling and power distribution during both routine cleaning and unplanned water exposure.
- Defense & Tactical Systems: SLAYSON® NEMA 6 / IP67 junction boxes are engineered for rapid field deployment and ground support equipment. These units provide a rugged, dust-tight barrier for mobile communications and tactical hardware that must survive extreme field conditions.

Frequently Asked Questions
Both IP67 and IP68 ratings address water submersion, but they are applied differently. IP67 defines protection against temporary submersion under standardized test conditions. On the other hand, IP68 allows the manufacturer to specify deeper or prolonged submersion parameters.
IP67 enclosures are commonly selected for standardized, commercially available applications. IP68 enclosures are specified for extended or deeper submersion.
Our NEMA 6 and IP67 enclosures are fully watertight when submerged for up to 24 hours up to the specified depth.
Note that they do not imply unlimited depth, duration, or operating conditions. Always review the specific enclosure datasheet to confirm suitability for the application.
The main difference lies in the duration of submersion. NEMA 6 is intended for temporary submersion. NEMA 6P is designed for prolonged or continuous submersion and includes additional corrosion-resistance considerations.
Our NEMA 6 enclosures are designed as a waterproof barrier against water and dust ingress for up to 1.5 meters for 24 hours. It’s the ideal enclosure for keeping key components free from water ingress while protecting against corrosion in marine environments.
NEMA 4X enclosures are also designed for outdoor use in harsh environments, specifically to resist dust, falling dirt, and water ingress.
While NEMA 4X can provide perfect protection in most outdoor environments, NEMA 6’s ability to remain submerged for a period of time gives it the edge in many environments.
NEMA stands for the National Electrical Manufacturers Association. NEMA enclosure ratings define levels of protection against environmental conditions, including dust, water, and corrosion.
IP stands for Ingress Protection. IP ratings are defined under IEC 60529 and describe protection against solid particles and liquid ingress using a two-digit code.
For more information, see our resources on what a NEMA 6P is equivalent to in IP.
NEMA 6 and IP67 ratings define protection against temporary submersion under controlled conditions.
IP67 indicates protection against immersion in water up to 1 meter for a limited duration, as defined by IEC 60529. NEMA 6 provides protection against temporary submersion and powerful water ingress, but does not specify a specific depth or duration.
