The Signature Series thread design allows connection and disassembly with only 1-1/2 turns, significantly faster than with thinner thread designs. Because the threads are thicker and more durable than traditional threads, they can also withstand tough use in the field.
Signature series extensions feature zinc-coated chromoly for added rust resistance. Extensions are offered in 1′, 2′, 3′, and 4′ lengths.
Please make sure any AMS samplers you intend to use together share a common connection type. Click here for information on the AMS connection types.
