Waterproof Rubber Seal Washer for RP-SMA & SMA to Seal Connector on Enclosure

Waterproof red silicone O-ring for RP-SMA-female and SMA female connector.

You have the option to include bulkhead nut and washer(s) (one for each silicone O-ring): The bulkhead nut and washer are used to mount an SMA-or RP-SMA female connector on an enclosure, case or Printed Circuit Board (PCB). The Bulkhead nut & washer are rust-proof 100% brass.

• Waterproof Rating: Using this O-ring with the bulkhead nut and washer (100% brass version) on an SMA or RP-SMA-female connector results in the connector having an IP68 rating. We automatically include the 100% brass version of the Bulkhead Nut & Washer set when you order it with the O-ring.
• If you do not need for the Bulkhead Nut & Washer to be rustproof, click here to order the version that is a non-rustproof brass alloy and save $0.03 per set (SKU BHNW).
• For outdoor applications (if using bulkhead nut & washer): Nickel-plated brass is the best option to rustproof / waterproof/ weatherproof RP-SMA and SMA antenna connectors.

We also offer (as a special order), RP-SMA-female and SMA-female connectors with a waterproof O-ring embedded in the flange. We can do this for bulk orders of cables with these connectors. Please inquire with Customer Service.

Waterproof Rating: Using this O-ring on an SMA or RP-SMA-female connector with a bulkhead nut and washer results in the connector having an IP68 rating:

The typical installation involves placing the O-ring on the outside of the enclosure port (and this is the IP68 level of protection). To be extra secure to protect against water ingress in the flat part of the D-ring (many RP-SMA and SMA female connectors have a D-flat), you could put an O-ring inside and outside the enclosure wall.

It is sealed when unmated: The nut, tightened against the o-ring and bulkhead, is what seals it and this remains in place when the connectors are unmated.

The inside diameter is 6mm, to clear the threads on the female connector.
