English Translation of Title:
Adapter JIC/ORB 3/4" x 3/4" – Waterjet Cutting Equipment Accessory (ID: 95702619)

Description, Purpose, Features, and Maintenance:

This component is a threaded hydraulic adapter that converts between JIC (Joint Industry Council) 37‑degree flare connections and ORB (O‑Ring Boss) port configurations, both with 3/4‑inch nominal sizes. It is specifically used in waterjet cutting systems to interface high‑pressure tubing, hoses, and pump manifold ports where different sealing standards must be joined.

Purpose:

• Bridges JIC flare fittings and ORB threaded ports within the same 3/4‑inch size class, enabling mixed‑standard system assembly.

• Provides a leak‑tight transition between pump discharge lines, attenuator connections, and cutting head supply hoses.

• Allows retrofitting or replacement of components without modifying existing port configurations.

• Serves as a critical interface in high‑pressure water circuits operating up to 4,000–6,000 bar (depending on system rating).

Features:

• Machined from high‑strength, corrosion‑resistant stainless steel or precipitation‑hardened alloy suitable for ultra‑high‑pressure water service.

• JIC end features a precision 37‑degree flare sealing surface for metal‑to‑metal contact.

• ORB end includes an integral O‑Ring groove with a compatible elastomer seal for face‑sealing against the port.

• Full internal bore design minimizes flow restriction and pressure drop.

• Hexagonal body section allows easy wrench engagement for installation and removal without damaging sealing surfaces.

• Passivated surface finish resists crevice corrosion and galling during repeated connections.

Maintenance:

• Before each installation, inspect both sealing surfaces: the 37‑degree flare for scratches or deformation, and the O‑Ring groove for debris or damage.

• Replace the O‑Ring each time the adapter is removed; use only seals rated for ultra‑high‑pressure waterjet service.

• Check flare surface for scoring; if deeper than 0.1 mm, replace the adapter to prevent leakage.

• Lightly lubricate threads and O‑Ring with water‑compatible lubricant (not petroleum‑based) to reduce friction and prevent galling during tightening.

• Torque to the recommended value for the specific port type; do not over‑tighten, as this can distort the flare or extrude the O‑Ring.

• Clean the adapter with a soft cloth and mild solvent before reassembly; avoid abrasive tools that could mar sealing faces.

• Store in protective packaging to prevent impact damage to the flare and O‑Ring surfaces.
