The needle is inserted into the Spectra line being spliced, and the end of the other piece of spectra line is inserted into the needle’s wire loop. As the needle is inserted into the line being spliced, the other piece of line is pulled along with it. When done, the needle is brought out of the line being spliced, and the end of the line attached to the needle wire loop is tightened to complete one side of the splice, or the terminating loop, as the case may be.

Typically, thicker walled tubing is used for these needles, as the focus is not on the needle’s internal open size, but on strength, and the always important overall small size. The primary size of the needle is the OD, or Outside Diameter, and what sizes of spectra lines it would best be used with.

We have two loop splicing needles in our special sizes group. Our X-Large loop needle is designed for use with very large hollow spectra lines not commonly used by most customers. And, our X-Small loop splicing needle is the only .025" OD in size and is the smallest spectra tool offered by anyone. It is built from a 304 stainless steel tube, as all our products, but because of its size, we have filled it with a solid 304 SS wire. This design gives it the strength of a tube, but it will not crease like a tube if it is ever bent. This needle can be bent and straightened without tube damage. It is the only one that can be used in the new 50# and below, smaller hollow spectra lines.
