Product Overview
A Cutting Tip That Carries Its Own Numbers On Its Body
Condition
New, and still in the Koike blister card. The clear formed shell is closed over the tip and sits on the printed red card, which reads GAS CUTTING TIP, KOIKE, MADE IN JAPAN and www.koikegroup.com, with a separate label at the top reading 102-D7-1 next to a circled A. Through the plastic the copper-toned body shows an even factory finish with some darkening across the taper, and the brass-toned seat end is bright with clean machined lands. The blister plastic is creased and wrinkled in places, the way stored packaging goes. Stock is five, so the photographed piece is representative of the group rather than the exact one you receive, and the tip is sold each.

Product Overview
The Koike 102-D7-1 is a gas cutting tip for oxy-fuel cutting, listed here under the acetylene fuel gas designation that matches the circled A appearing both on the package label and stamped into the tip body. The card carries the full part number 102-D7-1; the body itself is stamped with that circled A, a triangle symbol, 102, 7 bar, and 10-15mm. Koike publishes a cutting oxygen pressure and a plate thickness range for each tip in this family, so the stamped 7 bar and 10-15mm are the figures to match against the Koike tip chart for your torch, regulators and material. Not confirmed here - verify against the datasheet before use. At the working end the face carries a center cutting bore ringed by smaller preheat holes. The opposite end is brass-toned, machined into stepped sealing lands with small ports drilled through them, finishing in a rounded nose that seats into the torch head. No ruler appears in the photographs, so no dimension is stated here. The tip is marked Made in Japan on the Koike card.

- A millwright or field welder cutting plate in the range this tip is stamped for, who would rather read the number off the part than guess

Frequently Asked Questions
What do the markings on the tip actually say?
The copper-toned body is stamped with a circled A, a triangle symbol, 102, 7 bar, and 10-15mm. The package label reads 102-D7-1 with the same circled A. Koike lists an oxygen pressure and a plate thickness range for each tip, and these stamped figures are the ones to check against the chart for your equipment. Not confirmed here - verify against the datasheet before use.
Will this tip fit my torch?
It is a Koike 102-D7-1 with the brass-toned seat end shown in the photos. Seat style and torch compatibility are not confirmed here, so match the part number and the seat against your torch manual or Koike's tip chart before ordering. The photos show the seat end from two angles for exactly that reason.
Is it really unused, and what does the packaging look like?
It is listed New and it is still in the Koike blister card, with the clear shell closed over the tip. The plastic is creased and wrinkled from storage, and the copper-toned body has darkened somewhat in the photographs, which is what that finish does on a shelf. Nothing was removed from the package for these photos.
Why buy a single tip here instead of a box of them?
Because a cutting tip is a consumable you count out, not a case you commit to. Buy the one you need for the job in front of you, or a couple to sit in the tip drawer, without carrying a full box of a size your work may not call for again. Five are in stock and each one is sold individually, with the photographed piece representative of the group. Shipping is $8 flat rate, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
A cutting tip carries its whole working spec stamped into its own body, which is a good arrangement, because the paperwork never makes it back out to the torch cart. Match the numbers to your setup and this one goes back to turning oxygen into a straight edge.
