Sealing Ring · 1-1/2 in NPT · Steel · Green Finish · Nesco SR-15
SKU: CF-SR-15
1-1/2 in NPT sealing ring for electrical fittings and conduit entries where a tight seal is required. Commonly used to help reduce moisture and dust ingress at enclosures and fittings in commercial and industrial installations.
What this product is for
This sealing ring is used on 1-1/2 in NPT threaded electrical fittings to help create a tighter seal at the enclosure or hub entry. It is suited to conduit and fitting assemblies where moisture and dust resistance matter.
Use for
Use for commercial and industrial electrical installations, panel entries, and conduit terminations where a sealing ring is specified. It is commonly selected when matching a 1-1/2 in trade size fitting or hub.
Avoid for
Avoid using this item as a substitute for a listed gasket, hub, or sealing fitting where the assembly requires a specific certified component set. Do not assume hazardous location suitability unless the complete fitting assembly is listed for that use.
Best for
Best for electricians and maintenance teams replacing a missing or worn sealing ring on threaded electrical fittings. It is a practical choice when you need the correct trade size without replacing the full fitting.
Installed in
Typically installed at 1-1/2 in NPT conduit or fitting entries on boxes, cabinets, enclosures, and similar equipment. 1-1/2 in trade size is approximately 38 mm.
Why this product exists
Sealing rings help close the gap between the fitting and enclosure surface to improve the seal against moisture and dust. This supports cleaner, more reliable electrical terminations in demanding indoor or outdoor service conditions.
Compared with similar products
Compared with replacing a complete connector or hub, a sealing ring is the lower-cost service part when the fitting itself is still usable. Buyers should confirm trade size, thread type, and material compatibility with the mating fitting before ordering.
