Hose Box Inc. Product Lines & Series

Hose Box organizes its catalog into distinct kit families, so you can match a kit to a thread standard or repair scenario rather than sourcing fittings one at a time.

• Easy Pack series — hydraulic fittings kits configured by thread type, including BSPP, DIN Light, DIN Heavy, JIC, NPT, ORB, and ORFS/Face Seal layouts.
• Professional Series — fuller hydraulic fittings kits for shop and field technicians who need broader thread coverage in one case.
• Everyday Series Fitting Towers — stationary towers for organizing and refilling commonly pulled fittings.
• Emergency Hydraulic line — waterproof emergency kits assembled for on-site hose and fitting repairs.
• Cap & Plugs kits and Mini Packs — cap and plugs kits plus compact assortments for sealing and protecting ports during service.
• D.O.T. line — brass and composite D.O.T. brake fitting kits for vehicle air-brake lines.
• O-Ring kits — assorted seals to support ORB and Face Seal connections.

Cross-Referencing Hose Box Inc. Parts

When a Hose Box kit configuration is discontinued or a single fitting tile runs out, you do not have to replace the whole case. We cross-reference Hose Box kits by thread standard — BSPP, DIN, JIC, NPT, ORB, and ORFS/Face Seal — and supply equivalent and replacement fittings to rebuild or refill a kit to the same specification. Send us the kit name, the thread type, or a fitting marking, and we will identify the matching components. To match a discontinued Hose Box kit or refill a specific tile, request a cross-reference quote.
