Product Name: HP Collar, 1/4" – Part No. 10078426

Description:
The 1/4" HP Collar is a critical component of the high-pressure (HP) connection system in waterjet cutting equipment . It is a precision‑machined, anti‑vibration collar designed to work with 1/4” ultra‑high pressure (UHP) stainless steel tubing . Its primary function is to slide over the HP tubing and engage with a mating gland nut. When the gland nut is tightened, the collar creates a secure, vibration‑resistant metal‑to‑metal seal against the cone seat of the adapter or valve body .

Applications:

• Securing 1/4" high‑pressure water lines to on/off valves, check valves, and cutting heads .

• Used as part of the anti‑vibration hardware on intensifier pumps (e.g., SL‑VI series) to prevent loosening from pressure pulsations .

• Required for installing HP tubing in both 60KSI (4,137 bar) and 90KSI (6,200 bar) systems .

• Compatible with multiple brands (Flow, KMT, H2O Jet, OMAX), making it suitable for retrofits and general maintenance .

Features:

• High‑Strength Material: Machined from corrosion‑resistant stainless steel to withstand extreme waterjet environments .

• Anti‑Vibration Design: Engineered to dampen mechanical vibration and prevent threaded connections from loosening under continuous high‑pressure pulses .

• Standardized Fit: Precision‑machined for use with 1/4” HP cone adapters and gland nuts (e.g., P/N 400006-1, 10078459) .

• Low Weight: Approximately 7–9 grams, making installation and handling easier .

• Direct OEM Replacement: Replaces OEM numbers such as KMT 10078426, Flow A-2867, H2O 400006-1, and OMAX 200788 .

Maintenance:

• Regular Inspection: Check for signs of wear, galling, or corrosion, especially on the internal cone seat and threads .

• Lubrication: Apply a thin layer of high‑pressure anti‑seize to the mating threads only (keep the cone seat dry) to ensure proper torque and prevent thread seizure.

• Torque Compliance: Use a torque wrench to tighten the gland nut to the value specified in the equipment service manual (e.g., approx. 34 N·m / 25 ft‑lbs for 1/4” connections).

• Two‑Wrench Method: Always use one wrench to counter‑hold the fitting body and another to tighten the nut to avoid twisting the tubing.

• Replacement: Replace the collar if the internal threads are damaged, the cone seat is nicked, or if it shows signs of stress cracking .
