Is the INTERLOCK SAE 3000 Straight Flange End, Carbon Steel compatible with hose types 4SH, R13, and R15 and fitted with an O-ring seal for high-pressure use?

Yes. The INTERLOCK SAE 3000 Straight Flange End, Carbon Steel is compatible with hose types 4SH, R13, and R15 and is fitted with an O-ring seal (or alternative gasket) seated in the flange groove for reliable, high‑pressure sealing. Manufactured from carbon steel with durable galvanization, it provides corrosion and wear resistance suitable for demanding hydraulic applications.

What maintenance is recommended for the INTERLOCK SAE 3000 Straight Flange End, Carbon Steel to ensure long-term corrosion and wear resistance?

Recommended maintenance for the INTERLOCK SAE 3000 Straight Flange End, Carbon Steel: - Regular inspection: visually check flange surface, threads and sealing groove for pitting, scratches, deformation or wear every 250 operating hours or monthly in severe conditions. - O-ring/gasket care: inspect seal for cuts, hardening or extrusion; replace seals during scheduled maintenance or immediately if damage is found. Keep spare O-rings/gaskets of correct material on hand. - Corrosion protection: maintain galvanization by cleaning off dirt, salt and chemicals after exposure; apply light protective oil or approved corrosion inhibitor to exposed surfaces during long idle periods. - Cleaning: remove contaminants (dirt, debris, hydraulic fluid residue) with lint-free cloth and compatible solvent; avoid abrasive tools that can damage sealing surfaces. - Torque and fasteners: verify flange bolts are torqued to specified values and recheck after initial run-in; replace any corroded or stretched fasteners. - Compatibility checks: ensure hoses (4SH, R13, R15) and hydraulic fluids remain compatible and free of contaminants that accelerate wear or corrosion. - Environmental controls: where possible limit exposure to corrosive atmospheres, moisture and abrasive particulates; consider supplementary coatings or covers in extreme environments. - Record keeping: log inspections, seal replacements and any repairs to track wear patterns and schedule proactive maintenance. Following these steps preserves the component’s galvanization, prevents corrosion and reduces mechanical wear, extending the INTERLOCK SAE 3000 Straight Flange End, Carbon Steel service life.
