Product Series and Configurations

The fittings are categorized into multiple series, each tailored for specific connection types and installation needs:

RR01 & RR02: Straight stud fittings with external/internal hex keys for tight spaces, supporting various tube diameters and thread sizes.
RR03: Female BSP stud fittings in nickel-plated brass for tube diameters 4-10 mm.
RR04: Tube-to-tube straight unions for same or different diameters.
RR05: Reducers connecting tubes of different diameters.
RR06: BSP stem adapters for threaded port connections.
RR07: Bulkhead fittings for panel or wall pass-throughs with thickness limits.
RR08 to RR11: Stem and elbow fittings including male stems, fixed BSPT elbows, push-in plugs, and BSPT swivel elbows.
RR12 to RR16: Various swivel and extended elbows, including double swivel elbows with multiple articulation points.
RR17 to RR23: Stem elbows and T-joints, including BSP swivel tees and double swivel tees with hex wrench features.

Additional Product Types

RR24 & RR25: Swivel side tees with cylindrical (BSP) and conical (BSPT) threads for lateral connections.
RR26: Stem side tees for push-in stem connections.
RR27: Equal tees for uniform tube-to-tube junctions.
RR28: Equal H swivel unions offering four-way swivel connections.
RR29: Y pieces for three-way tube connections.
RR30 to RR35: Banjo bolts and fittings in single and double configurations with male/female threads and cylindrical washers for fluid or gas systems.

Dimensional Data and Ordering Information

Extensive tables provide detailed dimensions for each fitting type, including tube outer diameters, thread sizes, diameters (D1, D2, D3), lengths (L1 to L5), and wrench sizes (CH, CH1, CH2). Packaging quantities range typically from 10 to 50 pieces per package, facilitating inventory and project planning.

Key Recommendations and Usage Notes

Use nickel-plated brass fittings for general applications; stainless steel versions are recommended for enhanced corrosion resistance.
FKM seals should be selected for applications requiring temperatures up to 150 °C.
Pre-tefloned BSPT threads provide reliable sealing without additional tape.
Hexagonal keys on stud fittings enable installation in confined spaces.
Swivel elbows and tees allow flexible orientation to accommodate complex tubing layouts.
Verify dimensional compatibility to ensure proper fit and avoid installation issues.
Consider order quantities for efficient inventory management.
