PACKAGE CONTENTS - 5 PCS. of Marine Grade Tinned Copper 0000 Gauge (AWG) 5/16" Ring Battery Terminal Connectors / Lugs. 100% annealed tinned copper, providing a high degree of conductivity for maximum current flow when used as battery terminals. DURABILITY - Approved by OEMs, our Tinned Copper wire ring connectors are corrosion free; ideal for marine, automotive or outdoor use; salt spray tested to ASTMB117 standard. Special matte tin plating make these lugs as easy to Solder as it is to Crimp. WIDE APPLICATIONS - Selterm tinned copper lugs wire connectors have a close end pad design, keeping electrical components, battery and wire cables safe and act as waterproof wire connectors which prevents solder from leaking during installation of lugs or while using as a heat shrink wire connectors for your battery in Marine, Golf Carts, RV's, Automotive and other outdoor equipment. PERFECT FIT - Selterm provides freedom to choose from wide range of wire sizes, stud sizes, and pack quantities from 2 - 25 pcs. best suitable for all requirements and applications as a battery connectors. Superior material quality of tinned copper terminals lugs can be crimped or soldered. Use with a compatible copper cable; Audio wire may not be a direct fit. Recommend to check product dimensions to ensure a proper fit of the connectors. HEAVY DUTY WIRE LUGS - Our ring terminal connectors are tested to meet S.A.E conductivity standards J163 & J1811; UL listed to U.S. & Canadian safety standards and rated to 600V+ when properly installed; RoHS & REACH compliant; These Battery Wire Connectors are listed under UL File Number E254830. SELTERM Tinned Copper Battery Cable lugs are ideal for making Marine Grade Cables, Battery Cables & Welding Cables that are used in marine, outdoor and harsh environments. To ensure their anticorrosive properties, these lugs have been subjected to salt spray tests to ASTMB117 standard. Rigorous field testing in harsh winter environments in snow have also been conducted by OEMs that depend on these lugs. These Lugs can be crimped or soldered on and are UL & CUL listed and rated for up to 600V+, allowing use in a wide range of applications such as Boat Wiring, Trolling Motors, Car Audio, ATVs, RVs, Snowmobiles, Golf Carts, Automotive, Electric Powertrains, Off-grid Solar, Back-up Power & Battery Banks. The Cable Lugs are made from 99.9% pure seamless copper tubes that adhere to the ASTMB188 standard. The copper is malleable & ductile enough to withstand crimp force without cracking. The lugs are tin plated according to ASTMB545 standard to guarantee uniformity in the plating thickness. These copper lugs are tested to ensure they meet S.A.E conductivity standards J163 & J1811. The barrels of the lugs have flared end to ensure easy cable entry. The pads of the lugs are properly sealed at the ends to prevent any moisture or solder from leaking. Wire & stud sizes are clearly marked on the pads for easy identification during installation. The lugs are RoHS & REACH compliant.
