What are the port specs?

Port A: Male BSPP G1/8 to G2 (parallel) (Bonded-seal washer). Port B: Male BSPP G1/8 to G2 (parallel) (Bonded-seal washer).

What sizes are available?

G1/8 to G2. Larger or non-standard sizes are typically quoted on request.

What is the maximum working pressure?

up to 400 bar at smaller sizes; derates with size. The pressure rating tracks the lowest-rated component in the assembly — pair with appropriately rated host ports, hoses, and ferrules.

What materials and finishes are available?

Standard: carbon steel with zinc-plated, Cr3+ passivated, RoHS-compliant finish. Stainless steel 316 available on request for marine, chemical, or food-grade service.

Is this adapter interchangeable with other thread families?

BSP is a thread family in its own right and is NOT directly interchangeable with other families (BSP / JIC / NPT / Metric / ORFS / DIN). Use the appropriate thread-mix adapter (e.g., m JIC × m BSPT) when crossing thread families.

Do I need to crimp this onto a hose?

No — these are tube / port adapters, not hose ends. Use Indus crimp ferrules + Indus hose-end fittings for hose assemblies. These adapters thread into ports or join tube sections.

Common configurations are ex-stock from Dubai. Less-common thread × seal × size combinations typically ship within 7 working days from RFQ confirmation.

Product description

The Thread Reducer is a Reducer hydraulic adapter in the BSP family. Thread Reducer — BSP family reducer for hydraulic line interconnection. RFQ-only; standard Indus zinc-plated carbon-steel construction.

Construction

Body configuration: Reducer
Port A: Male — BSPP G1/8 to G2 (parallel) (Bonded-seal washer)
Port B: Male — BSPP G1/8 to G2 (parallel) (Bonded-seal washer)
Material: Carbon steel (stainless steel available on request)
Surface treatment: Zinc-plated, Cr3+ passivated, RoHS-compliant

Performance

up to 400 bar at smaller sizes; derates with size. BSP family — British Standard Pipe — ISO 228-1 (BSPP, parallel) and ISO 7-1 (BSPT, taper). BSPP requires a separate seal (bonded-seal washer, ED seal, 60° cone, or flat-face); BSPT is taper-on-taper self-sealing.

Applicable Standards

ISO 228-1 (BSPP)
ISO 7-1 (BSPT)

How to order

Specify (a) the host port size and thread spec on each end, (b) any special seal requirements (bonded seal vs ED seal vs cone seat), and (c) whether you need stainless-steel construction or non-standard surface treatment. Indus engineering will confirm the correct part number against your equipment.

Companion products

Pair with the appropriate Indus tubing or hose ends. For tube assemblies use Indus DIN 2353 cutting rings and end nuts. For hose assemblies pair with Indus crimp ferrules and the matching hose grade.
