SMC KV2 fittings are made from rugged ultraviolet and vibration resistant composite. One-touch technology makes tube insertion (with strong tube holding force) and removal easier. KV2's patented seal allows tube cut angles to be well above the heavy vehicle industry standard. KV2 meets FMVSS 571.106, SAE J1131 and SAE J2494 standards. The SMC KV2 DOT Fitting is a direct replacement for the PTC cartridge fittings found in Accuair & Air Lift Performance air suspension manifolds.Fits: Accuair VU4 valve manifold, Airlift Performance 3S / 3P / 3H valve manifoldsFeatures:Direct replacement for Accuair VU4 & AirLift Performance 3S/3P/3H manifoldsAvailable in 1/4 and 3/8 PTCRugged & durable brass & composite constructionIncludes:SMC PTC Cartridge Fitting (1/4 or 3/8 PTC)SMC Part # KV2H07-Q07 (1/4 PTC), KV2H11-Q11 (3/8 PTC) Brand (Manufacturer) InfoSince its establishment, SMC has been a leader in pneumatic technology, providing industry with technology and products to support automation based on the guiding principle of “contributing to automation labor savings in industry.” Over the past 50+ years, SMC's products have become established as a recognized international brand through sales, technical, supply and after sale services in world markets.
