Accessories

Inserts into Dome Nut for a liquid tight seal!

*Metal Parts use different O-Rings.

Accessories - O-Rings & Seal Rings

For Strain Relief Fittings - PG / NPT / Metric

Accessories - Strain Relief Blind Plugs

Nylon - Fits PG / NPT / Metric Threads

If Type NEMA 4x or 6 (IP 68 or IP 69K - Submersible) is required, O-Rings or

Seal Rings should be used when mounting Strain Relief Fittings to a control

panel, secured with a Locking Nut. The straight Strain Relief Fittings feature

a molded O-Ring groove. For these ttings the O-Ring is the best solution.

The Snap Elbows and some of the Conduit Fittings don’t have a recess for

an O-Ring. In that case, the Seal Ring would be the better choice, unless

the hole can be beveled to accommodate an O-Ring.

These non-threaded Plugs are made of

Black Nylon (RAL 9005) and fit PG, NPT

and Metric Strain Relief Fittings.
