The Adaptall 9277 Straight Male JIS x Male ORB hydraulic adapters, made from carbon steel, provide secure and leak-proof connections for hydraulic systems under medium to high pressure. ORB (SAE Straight Thread O-ring Boss) fittings use a male straight UNF thread with an O-ring that compresses into a chamfered surface in the female port, creating a reliable seal. These adapters are commonly made of materials like carbon, nickel-plated carbon, and stainless steel, and utilize Buna-N or Viton, 90 Durometer O-rings for optimal sealing. JIS (Japanese Industrial Standard) tapered pipe threads, as per JIS B 0203, are similar in design to BSPT threads and are interchangeable with BSPT connections. Additionally, JIS parallel pipe threads, used in 30° Male Inverted Seat and Female (Cone) Seat connections, are comparable to BSPP threads and are interchangeable with BSPP connections. These adapters are designed to offer a high-performance, leak-tight seal, ideal for fluid power applications in various industries.
