Hose Couplings

RYCO Hydraulics Hose Couplings

Premium Hydraulic Hose Couplings Built for Mining, Industrial & High-Pressure Applications

Ryco Hydraulics hose couplings are engineered for high performance, safety, and compatibility across demanding hydraulic systems — especially within heavy-duty mining environments. Designed to match specifically with RYCO’s advanced ISOBARIC hose families, these couplings ensure reliable sealing, maximum efficiency, and safer assemblies across harsh operating conditions.

Whether you need a hydraulic hose coupling for underground mining, hydraulic hose quick couplings for on-site service, or hydraulic hose repair couplings for maintenance in the field — RYCO provides a world-leading solution for accurate fitment, pressure integrity, and long service life.

Why RYCO Hydraulics Couplings are Different

A common misconception in the market is that if a coupling and hose share the same SAE or EN (DIN) specification — they will automatically match correctly.

This is not true.

As clearly stated in SAE J517:

“SAE J517 Hose from one manufacturer is usually not compatible with SAE J516 connectors supplied by another manufacturer.”

This is why RYCO develops its own hydraulic hose specification and tighter dimensional tolerances — exceeding SAE/EN ranges. When paired with RYCO hose, RYCO couplings produce safer, stronger and longer-lasting matched assemblies.

Key Features of Ryco Hydraulic Hose Couplings

• Designed for compatibility with RYCO ISOBARIC hose families

• Tighter dimensional tolerances for superior crimp integrity and sealing

• Engineered specifically for heavy-duty mining, industrial and mobile hydraulic systems

• Available in hydraulic hose coupling, hydraulic hose quick coupling and field-attachable formats

• World-class performance, reliability, safety and lifecycle durability

• Fully traceable branding for ferrules and inserts (improved part numbering maintained since 2013)

Technical Standards Referenced

• SAE – Society of Automotive Engineers

• EN / DIN – European hydraulic system standards

• ISO – International Organization for Standardization

• AS – Australian Standards

RYCO couplings are designed to excel beyond minimum tolerances — delivering safer assemblies with reduced failure risk.

Types of RYCO Hydraulic Hose Couplings & Their Functions

RYCO Field Attachable, K & L Series Hose Couplings

Gerrard Hydraulics supplies a full range of genuine RYCO coupling systems for high-pressure, heavy-duty and mining hydraulics. RYCO hose + RYCO couplings must be used as a matched engineered system for maximum reliability, pulse life and safety.

Field Attachable Systems – K & L Series

RYCO K and L field attachable couplings are designed for on-site assembly and hose replacement using standard hand tools – ideal for remote area maintenance where crimping machinery is not available. These models consist of hose-specific ferrules and a common insert, and can be ordered individually or as a complete assembly.

Series fitment notes:

• K Series: Ferrules not available for T1A & T1D in -20, -24, -32. Use A Series (requires skiving).

• L Series: Ferrules not available for T2A, T2D & RQP2 in -24, -32. Use B Series (requires skiving).

Temperature caution: Do not use field attachable couplings on RQP1 / RQP2 hoses at maximum pressure above 121°C (250°F). Can be used above this temp at reduced pressure.

One-Piece Crimp Range – K / T6000 Series

K reference also aligns with RYCO’s premium T6000 Series one-piece crimp couplings for wire spiral hose (420 bar / 6100 psi). Uses the heavy-duty Code 62K flange with a long taper clamp design for extreme durability and million-cycle performance. No skiving required.

L-Series Quick Release Couplings (LQ Series)

Designed for frequent connect/disconnect hydraulic applications. Features single-action sleeve operation, multiple locking balls, full spanner hex, and rubber poppet sealing to reduce leakage risk.

Other RYCO Fitting Models We Supply

T2000 Series • T4000 Series • T7000 Series • 8000 Series Push-On • 33000 Series Suction & Return • Code 62K High-Pressure Flange Systems

K+ Plating System: Most modern RYCO fittings now include K+ corrosion-resistant plating for extended service life in harsh environments.

Additional note: RYCO Jseal™ JIC fittings provide up to double the working pressure of standard JIC connections.
