No 4R Reducing Union Fittings Compression Tube Joiners_Imperial x BSP_Compression Fittings_Products

Technical Overview

Product Overview

Our internal compression fittings are highly versatile and widely used in the pneumatics industry. Designed for high-vibration environments, the internal compression nut provides extra tube support to ensure a secure, leak-free connection. No specialized tools are required for installation.

Key Features

•High Vibration Resistance: Extra tube support prevents loosening in heavy-duty applications.

•Easy Installation: Requires minimal tube preparation and no special tools.

•Complete Assembly: Includes compression nut, universal sleeve, and brass body.

•Thread Type: Pipe Thread BSP - Tapered Male (R series) and Parallel Female (Rp Series).

Technical Specifications

•Working Pressure: 0 to 3500 kPa (0-500 PSI), depending on tube size and media.

•Material: Premium Brass.

Dimensions & Drawings

Assembly Instructions

1.Cut and Clean: Cut the tubing square. Remove all burrs and clean off any loose cuttings.

2.Prepare Tubing: For metallic tubing, skip to step 3. For non-metallic tubing, insert a support spigot into the end of the tube first.

3.Insert Tubing: Loosen the nut by a half turn and insert the tube into the fitting. Push it firmly through the sleeve until it hits the tube stop and cannot go any further.

4.Tighten Nut: Tighten the nut by hand until finger-tight. Then use a wrench to tighten it to a spanner-firm position. (Caution: Do not over-tighten).

5.Leak Test: For pneumatic applications, apply a soapy water solution to check for bubbles. For hydraulic applications, visually inspect the joint for any fluid leaks.
