The Best Hollow Spectra Threading & Splicing

DaHo Hollow Spectra Threading Needles
The new DaHo Threading Needles are shown above. As you can see, they have been sized by their length so if a customer has more than one of them, they can stand them on their open end and find the one they want by its length, compared to all the other threating needles. Our smallest threading needle, the 10 to 20# size, has a length of 5.3". Each larger threading needle is .1" longer than the last, with our largest 400 to 500# size being 6.5" in length. When we started, we spent a year gathering all of the requested features for our new needles. Having some way to identify the threading needle sizes was one that was requested many times. Due to their size and materials, the length was the only way to address this request.
The DaHo Hollow Spectra Threading Needles are hollow inside, except for the point, so monofilament or fluorocarbon line can be inserted into the needle. Then, the needle with the internal mono/fluoro line, is inserted, or threaded, into the hollow center section of the spectra braid. The needle, and attached mono/fluoro line, is typically inserted inside of the spectra from 3 to 5 feet to provide the best strength of the join. Because of the slick surface of the mono/fluoro line, the end point of the spectra must be finished to secure it to the mono/fluoro line. This finishing is usually done by gluing, serving, crimping, or some combination of these attachments, to the spectra line end. This ensures the join will not slip before the compression pressure occurs in the braid of the hollow spectra line to hold the joined lines together.
The primary size of the threading needle is the ID, or Internal Diameter, indicating the approximate size of the mono/fluoro line that it will fit inside. The threading needle size you need is determined by the size of the mono/fluoro line you are using. The ID sizes of our threading needles can vary up to .002" due to the Stainless Steel Hypodermic tube manufacturing process. This is the standard acceptable size variance of the SS tubes we use to make our needles. As we receive new shipments of needles, the IDs may change up to this .002" size. It is recommended that you select a needle that is at least .002" larger than your line for ease of use. It can also be difficult to fit an exact size of line into a needle. If you have a problem with your line not fitting into one of our needles, please send us an email and we will analyze and resolve the problem.
We have created PDF and Excel spreadsheet charts that show all of the line brands and sizes that we could find. These charts show which of our threading needle sizes should be used for that brand and size of monofilament and fluorocarbon lines. Please click here to view or download these charts. On these threading needle size charts, we have included the .002" size variance to ensure the selected threading needle size will fit your line. When you are done, you can return here by selecting the back arrow on the left side top of each window.
If your line is not on our charts, your line size can usually be found on the spool the line was purchased on, or by visiting the line manufacturer’s website. You will usually want to get a needle that will fit the line you are using, and provide and additional .002" of 'free' space to ease the insertion of your line.
If the mono/fluoro line is too large for the needle, you will have to cut it down, which is not much fun to do. The needles will hold smaller sizes of mono/fluoro line, up to a point, without issue. We offer most typically used sizes in our standard product offerings. We also offer 'special' sizes of needles for use with very small and large mono/fluoro lines, that are not commonly used. All are named for the typical size range of mono/fluoro that they will hold, but you really need to select your needles by the actual size of your mono/fluoro line, as the line size can vary a lot.
In Threading needles, we typically use thinner walled tubing to manufacture the needle. This is so the overall size of the needle will remain as small as possible, while offering the largest interior size to hold the monofilament or fluorocarbon line you are using. Thinner is definitely better in this case, and our needles are the thinnest available…

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.
We make five different sizes of DaHo Loop Splicing Needles. The special sizes group needles are shown in blue below. They are listed in the table below:
|Model||Description||OD Size||Spectra Sizes|
|LS0250||X-Small Loop Splicing Needle||.0250"/.635mm||50# to 80#|
|LS0355||Small Loop Splicing Needle||.0355"/.90mm||60# to 130#|
|LS0420||Medium Loop Splicing Needle||.0420"/1.06mm||80# to 200#|
|LS0500||Large Loop Splicing Needle||.0500"/1.27mm||130# to 300#|
|LS0650||X-Large Loop Splicing Needle||.0650"/1.65mm||300# and up|
DaHo Reverse Latch Splicing Needles
Our newest line of needle products are our DaHo Reverse Latch Splicing Needles. The design for these products came from Jerry Brown, a pioneer in the development of hollow spectra fishing lines. We appreciate his design as this product brings some unique features and ease of use characteristics that we try to provide in all our products. Below is a picture showing the ends of the new DaHo Reverse Latch Needle in detail:
In the past, one of the first tools available to work with hollow spectra lines were latch needles that originally came from fabric knitting machines. They are still used today, but our Reverse Latch needle is the only tool available that uses the latch mechanism as it was designed to be used - to be pulled through the line, keeping the latch mechanism closed by the line's internal pressure. Without our 'reverse' use of the latch mechanism, the old knitting machine latch needles have to be pushed into the hollow spectra lines causing to latch to open, and usually resulting in significant damage the line's fibers.
Many of the loop creation and splicing techniques require that a line be released by the tool, while it is threaded up another line. Normal loop splicing needles will not work in these situations as they cannot release a line from the loop. In those types of operations, our DaHo Reverse Latch Splicing Needles allow the latch to open, releasing the held line, when needed. Also, since they are now attached to our standard 6" needles, so you can now make longer loops and splices without the limitations of the old latch needles. With our Reverse Latch needle, the latch is always the trailing end of the tool.
We are now offering three sizes of the Reverse Latch Splicing needle. The following table shows the details of the DaHo Reverse Latch Splicing Needles:
|Model||Description||OD Size||Spectra Sizes|
|RL0355||Small Reverse Latch Needle||.0355"/.90mm||60# to 130#|
|RL0420||Medium Reverse Latch Needle||.042"/1.06mm||80# to 200#|
|RL0500||Large Reverse Latch Needle||.050"/1.27mm||130# to 300#|
