Product ID: BV701184 – HP Gland Nut / High-Pressure Gland

Description:
This component is a high-pressure (HP) gland nut designed for waterjet cutting systems . It is a specialized threaded fastener used to secure and seal high-pressure tubing connections, typically at the interface between the high-pressure line and components such as cutting heads, valves, or fittings . This gland nut is rated for ultra-high pressure operation .

Applications:

• Used in waterjet cutting machines to connect high-pressure water lines to cutting heads, dump valves, check valves, or intensifier pump outlets .

• Installed on high-pressure tubing with standard outer diameter, typically compatible with 0.25 inch or 0.562 inch OD nozzle tubes .

• Suitable for both pure water and abrasive waterjet systems operating at pressure ratings from 60,000 PSI to 90,000 PSI .

Features:

• Manufactured from high-strength, corrosion-resistant material such as hardened stainless steel to withstand extreme pressure cycling .

• Rated for ultra-high pressure operation, typically certified for 60,000 psi (approximately 4,137 bar) up to 90,000 psi (approximately 6,200 bar) .

• Precision-machined threads ensure proper fit with high-pressure collars, adapter cones, and mating fittings .

• Designed with wrench flats, typically 1.250 inches across, for reliable torquing during assembly and maintenance .

• Anti-vibration configuration helps maintain secure connections under continuous pressure cycling and machine vibration.

• Engineered to compress a conical ferrule or seal against the mating tubing to create a leak-proof high-pressure seal .

Maintenance:

• Before removing a gland nut, fully depressurize the waterjet system and follow lockout/tagout procedures.

• Use the correctly sized wrench on the wrench flats; do not use pipe wrenches or pliers that may damage the nut surfaces.

• Clean the gland nut threads and mating surfaces thoroughly during each service to remove debris, old seal material, or corrosion.

• Inspect threads for signs of damage, galling, stretching, or corrosion; replace the gland nut if any deformation is found.

• Check the wrench flats for rounding or damage; damaged driving surfaces can lead to improper torque application.

• Inspect the conical sealing surface inside the gland nut for erosion, cracking, or wear caused by high-velocity water flow.

• Apply a thin layer of high-pressure compatible lubricant to threads before reassembly as specified by the equipment manufacturer .

• Tighten the gland nut to the specific torque value listed in the equipment service manual; over-tightening may damage threads or seals, while under-tightening may cause high-pressure leaks.

• When replacing the gland nut, ensure the mating cone adapter or ferrule is also inspected and replaced if worn.

• Replace the gland nut if it shows any signs of cracking, stress corrosion, or previous overtightening.
