RI-R 1 R 3/4WD belongs to the Male-female reducing adaptor BSP cylindrical with captive seal family in DICSA’s DIN 2353 Pipe fittings technical documentation.
The DIN 2353 catalog identifies the tube-side size and series separately from any stud thread. Straight, elbow and tee arrangements describe the connection layout; the dimensional drawing identifies the adjoining interfaces and installation space.
The catalog groups this component under Straight male stud couplings. The model table specifies R1, R2, Working (bar), L, L1, L2, HEX 1. These designations should be read together with the dimensional drawing when matching the component to the adjoining tube, fitting or mounting arrangement.
Catalog material: Mild Steel.
Thread designations are listed by connection position; matching nominal size also requires the same thread form and sealing geometry.
