Crouse-Hinds GASK643 Neoprene Replacement Gasket for GRF Enclosures

The Crouse-Hinds GASK643 is a neoprene replacement gasket engineered for use with Crouse-Hinds GRF-series conduit body and device enclosures. Made from durable neoprene material, this gasket is designed to create a reliable seal between mating enclosure surfaces, helping maintain the weathertight integrity of the assembly it is installed on. As a genuine Crouse-Hinds component, the GASK643 is intended as a direct-fit replacement part for maintenance and repair of existing installations using compatible GRF hardware. Electrical contractors and maintenance technicians rely on properly matched replacement gaskets like the GASK643 to restore a compromised seal without the cost or downtime of replacing an entire enclosure assembly, making this a practical stocked spare for facilities that run Crouse-Hinds GRF-series equipment.

Key Features

  • Neoprene Construction: Molded from neoprene material for flexibility and resistance to compression set, supporting a consistent seal at the enclosure joint over repeated service cycles.
  • GRF-Series Compatibility: Sized and shaped to fit Crouse-Hinds GRF-series enclosures as a direct replacement gasket, eliminating guesswork during field repairs.
  • Sealing Function: Positioned between mating surfaces to help block moisture and contaminant intrusion at the joint, supporting the weathertight performance of the enclosure assembly.
  • Genuine Crouse-Hinds Part: Manufactured to Crouse-Hinds specifications for consistent fit and performance when replacing worn, cracked, or compressed gaskets.
  • Maintenance-Ready: Simplifies field repair by allowing technicians to restore the seal on existing GRF enclosures without replacing the entire assembly, reducing material cost and labor time.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Crouse-Hinds GASK643 – Frequently Asked Questions

1) What is the Crouse-Hinds GASK643 gasket used for?
The GASK643 is a neoprene replacement gasket for Crouse-Hinds GRF-series conduit body and device enclosures. It sits between the mating enclosure surfaces to block moisture and contaminant intrusion at the joint, restoring the weathertight seal on an assembly whose original gasket has gone hard, cracked, or taken a compression set.
2) Will the GASK643 fit any Crouse-Hinds enclosure, or only certain ones?
Only GRF-series hardware. The GASK643 is sized and shaped as a direct-fit replacement for Crouse-Hinds GRF-series enclosures, so it is not a general-purpose gasket you can cut in on another series or body style. If the cover you are resealing is not GRF, this is the wrong part.
3) Do I have to replace the whole conduit body if the gasket on my GRF enclosure is shot?
No. That is the point of stocking the GASK643. A technician pulls the cover, replaces the gasket, and the existing GRF assembly goes back into service with its seal restored, which avoids the material cost and downtime of swapping the full enclosure.
4) Is neoprene the right gasket material for an outdoor electrical enclosure?
Neoprene is what Crouse-Hinds specifies here, and the GASK643 is molded from it for flexibility and resistance to compression set, so the joint keeps sealing through repeated cover removals rather than staying flattened after the first service call. That matters on enclosures that get opened for inspection on a maintenance schedule.
5) What part number do I order for a GRF gasket, and is it a genuine Crouse-Hinds part?
Order Crouse-Hinds GASK643. It is a genuine Crouse-Hinds component manufactured to Crouse-Hinds specifications, which is what gets you the original fit and material performance when resealing GRF hardware. There is one model, no size or finish choices to specify.
6) My GRF enclosure cover is leaking - do I replace the gasket or the whole box?
If the enclosure body and cover are sound and only the seal is worn, cracked, or compressed, the Crouse-Hinds GASK643 neoprene gasket restores the weathertight joint without replacing the assembly. If the enclosure itself is damaged, you are into a full replacement unit instead, such as the Hoffman A12124GSC screw-cover gasketed enclosure at 12 inches by 12 inches by 4 inches.
7) Should I keep replacement enclosure gaskets on the shelf for a preventive maintenance program?
If your facility runs Crouse-Hinds GRF-series equipment, yes. The GASK643 is a practical stocked spare: gaskets are the wear item on a weathertight enclosure, and having the matched part on hand means a failed seal found during a PM round gets closed out the same visit instead of waiting on an order.
