Custom Enclosures Protect Parts & Reputation

Featured Product from Web Seal Inc.


Enclosures, with doors, ports and accessories, involve irregular mating surfaces that require careful selection of a seal technology to keep your products secure.  Such enclosures may involve:

  • Semiconductors
  • Digital equipment
  • Manual, magnetic and solid-state starters and controllers
  • Thermal, magnetic and solid-state overload relays
  • Pushbutton stations, selector switches and pilot lights
  • Control circuit switches and relays
  • Float, flow, pressure and vacuum-operated switches
  • Resistors and rheostats, including those for heating and lighting, and motor generator fields
  • Proximity switches
  • Time-delay relays and switches
  • Control devices for industrial heating and lighting
  • Programmable controllers

 Enclosure gaskets that safeguard your products from outside environmental elements can be designed for ingress protection against human interference, moisture absorption, gases, vapors, dirt, dust and other particulates; to resist mildew, UV and ozone intrusion; and to shield against electromagnetic and radio frequency interference ( EMI/RFI).  Enclosure gaskets can also be designed to block out noise or other interference created by internal components.

A wide selection of materials are available from Web Seal including solid elastomers, thermoplastic elastomers; flexible cellular sponges and foams; O-rings, shaft seals and special forms; composite gasketing; and coated fabrics.

  • UL 157 – Standard for Safety of Gaskets and Seals
  • UL50 /UL50E – Enclosures for Electrical Equipment Standards
  • UL508A – Standard for Industrial Control Equipment/Panels
  • UL94 – Flammability Standards
  • NEMA – rating system of the National Electrical Manufacturers Association regarding types of environments in which electrical enclosures can use used and the ability of fixed enclosures to withstand certain environmental conditions
  • IEC – rating that defines levels of protections against foreign objects entering electrical enclosures

 

From simple to complex geometry, and from miniature to extra-large sizes, Web Seal can provide the optimal custom enclosure gaskets for your specifications, as well as rapid prototypes and material samples.
