Is the JIC adjustable screw connection with carbon steel BSP socket, type LE-BG, compatible with standard O-rings for sealing and does the retaining ring ensure vibration resistance?

The JIC adjustable screw connection with carbon steel BSP socket, type LE-BG Format uses an O-ring for sealing (as stated: "seal with O-ring and retaining ring"), so it is compatible with standard O-rings provided the O-ring material and dimensions match the applicationâs pressure, temperature and fluid compatibility requirements. The included retaining ring is intended to secure the O-ring and the assembly; it provides retention that increases resistance to loosening and helps maintain the seal under vibration. For high-vibration or dynamic applications, select appropriate O-ring material and hardness and verify retaining ring design and installation torque.additionally consider secondary anti-vibration measures if required.

Can the JIC adjustable screw connection with carbon steel BSP socket, type LE-BG, be used in saline or corrosive environments when galvanized and sealed with an O-ring?

The JIC adjustable screw connection with carbon steel BSP socket, type LE-BG Format, galvanized and sealed with an O-ring offers limited corrosion resistance in saline or highly corrosive environments. Hot-dip or electro-galvanizing provides superficial protection but is prone to pitting and coating breakdown under prolonged salt exposure or aggressive chemicals. The O-ring gives fluid tightness but does not protect the base metal from galvanic or crevice corrosion. For reliable long-term service in saline/marine or strongly corrosive atmospheres, stainless steel (e.g., 316) or specially coated materials are recommended. If short-term or occasional exposure only, and with regular inspection and maintenance, the galvanized LE-BG may be acceptable; for continuous exposure choose corrosion-resistant materials.

Q: What torque is recommended for installing the JIC adjustable screw connection with carbon steel BSP socket, type LE-BG to ensure O-ring sealing and retaining ring security?

For the JIC adjustable screw connection with carbon steel BSP socket, type LE-BG, tighten to the following recommended torque to ensure proper O-ring sealing and retaining ring engagement: - For sizes 1/8" BSP: 20â25 Nm - For sizes 1/4" BSP: 30â35 Nm - For sizes 3/8" BSP: 45â55 Nm - For sizes 1/2" BSP: 65â75 Nm - For sizes 3/4" BSP: 90â105 Nm - For sizes 1" BSP: 120â140 Nm Notes: - These values assume use of the specified carbon steel, galvanized fitting with factory O-ring and retaining ring. - Apply torque gradually and verify thread engagement; do not exceed upper limits to avoid damaging the O-ring or deforming the retaining ring. - If assembly includes pipe sealant or lubricants, adjust torque downward as necessary per sealant manufacturer recommendations. - When possible, confirm with manufacturer-specific torque tables for critical installations.
