We believe it’s important \u003cbr\u003eto support US manufacturing, and our supplier \u003cbr\u003epasses that test with flying colors. Not only is \u003cbr\u003eproduction based in the USA, but feed stock \u003cbr\u003eraw materials such as Nylon, PVC’s, and ETP \u003cbr\u003ecopper strip are also of domestic origin…this \u003cbr\u003eis equally important in our view!\u003cbr\u003e\u003cbr\u003eVertical integration means everything is \u003cbr\u003ebasically done in-house, top to bottom. Starting \u003cbr\u003ewith the bulk nylon and PVC (polyvinylchloride) \u003cbr\u003epellets, these are blended for proper coloring \u003cbr\u003eand then injection molded or extruded into the \u003cbr\u003efinal insulator. The copper used comes in giant \u003cbr\u003ecoils and is processed through progressive die \u003cbr\u003estamping equipment to produce the raw \u003cbr\u003eterminals. They even make all their production \u003cbr\u003etooling in house too.\u003cbr\u003e\u003cbr\u003eGetting into the weeds:\u003cbr\u003eETP! What’s that? ETP stands for “Electrolytic \u003cbr\u003eTough Pitch”. Huh??\u003cbr\u003eShort Answer: ETP is the highest grade of \u003cbr\u003eelectrical conductivity copper available. In terms \u003cbr\u003eof conductivity the next level up is silver, which is \u003cbr\u003eobviously unreasonable for everyday wire \u003cbr\u003eterminal applications. So back in the day the \u003cbr\u003eterm “tough pitch” originated from the time when \u003cbr\u003emolten copper, after refining, was cast into ingot \u003cbr\u003emolds. During refining the copper was oxidized \u003cbr\u003eto remove impurities, and then reduced by \u003cbr\u003ehydrogen to give the correct oxygen level. To \u003cbr\u003emonitor this process a small samples was taken \u003cbr\u003eand the solidification surface observed. If the \u003cbr\u003esurface sunk there was too much oxygen. If it \u003cbr\u003ewas raised there was too much hydrogen. If it \u003cbr\u003ewas level (correct pitch), the oxygen level was \u003cbr\u003ecorrect and the properties were good; in other \u003cbr\u003ewords “tough”, and hence the term “tough pitch”.\u003cbr\u003e\u003cbr\u003eAnnealing is the process of controlled heating of \u003cbr\u003ethe raw terminal. This is required after cold \u003cbr\u003eforming to relieve the stresses that are created in \u003cbr\u003ethe material during cold forming. This restores \u003cbr\u003eflexibility to the cold worked terminal. Some \u003cbr\u003emanufacturers will skip this step to save money. \u003cbr\u003eCheap terminals will be brittle; you can \u003cbr\u003edemonstrate this by grabbing the terminal pad \u003cbr\u003eand bending it back and forth. If it breaks or \u003cbr\u003ecracks, or is difficult to bend, you’ve got a cheap \u003cbr\u003eterminal. Vibration can do this to terminals in the \u003cbr\u003esame manner as your bending it. You get what \u003cbr\u003eyou pay for! \u003cbr\u003e\u003cbr\u003eInsulation: We only use extruded insulation for \u003cbr\u003eour butt connectors (as do all other manufacturers). \u003cbr\u003eMolded nylon or vinyl insulation is superior to \u003cbr\u003eextrusions and much less likely to split while \u003cbr\u003ecrimping. All of our terminals with insulation have \u003cbr\u003ea flared or funneled entry, which allows for easier \u003cbr\u003ewire insertion with no hang-ups. For our heat shrink \u003cbr\u003eterminals we top quality genuine 3M heat shrink \u003cbr\u003etubing. Nylon insulation is more pliable (and thus \u003cbr\u003eeasier to crimp) and has better heat resistance than \u003cbr\u003evinyl. Heat shrink tubing provides the best \u003cbr\u003eprotection against moisture intrusion. Vinyl (PVC) is \u003cbr\u003ethe most economical and is suitable for general\u003cbr\u003epurpose applications.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\u003c\/span\u003e\u003c\/div\u003e\u003c!-- End Description --\u003e\n\u003cdiv style=\"font-size:12px;clear:both\" align=\"center\"\u003e\n\u003cimg src=\"https:\/\/www.sixbitsoftware.com\/images\/tagline.jpg\" align=\"absbottom\" border=\"0\" alt=\"Powered by SixBit\" longdesc=\"https:\/\/www.sixbitsoftware.com\/images\/tagline.jpg\"\u003e\u003cbr\u003ePowered by SixBit's eCommerce Solution\u003c\/div\u003e","brand":"Industrial Tec Supply","offers":[{"title":"Default Title","offer_id":43087751708806,"sku":"TR1810N(100","price":7.88,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0089\/9838\/7774\/files\/57_241d72e6-962c-4202-91f7-bae6d62449c2.jpg?v=1769732396","url":"https:\/\/industrialtecsupply.com\/products\/mvp-100-red-18-22-awg-nylon-insulated-ring-terminals-10-stud-made-in-the-usa-1","provider":"Industrial Tec Supply","version":"1.0","type":"link"}
