The nickel-plated brass body resists corrosion in indoor or sheltered outdoor use, and the attached chain keeps the cap from walking off on a busy rack or test bench. This cap is designed for TNC jacks — the threaded coupling on the cap matches the TNC interface, so it screws on hand-tight and seals the port. It does not fit BNC, N, or other thread patterns; stick with TNC jacks and you are good. ## NRND — Plan Your Sourcing The 000-78750-RFX carries a Not Recommended for New Design (NRND) status. That means Amphenol RF is not actively promoting it for new builds, but it is still available through distribution for existing designs or replacement needs. Mates with any standard TNC jack — the threaded coupling matches the TNC interface. The cap does not provide an RF seal; it is a mechanical and environmental cover only.","metaTitle":"Amphenol RF 000-78750-RFX TNC Cap Cover, NRND, Nickel Brass","metaDescription":"Amphenol RF 000-78750-RFX TNC cap cover, nickel-plated brass, chain included.
