Multi-Fit Air Coupling | 13mm Hose Tailpiece | 35 Bar | Steel | UK Stock

Overview

The definitive quick-connect solution for 13mm bore air hose installations — built to perform under sustained pressure, day after day.

This Multi-Fit Air Coupling with 13mm Hose Tailpiece delivers a fast, leak-free connection between your compressed air hose and pneumatic tools, air lines, or workshop equipment. Its multi-fit design ensures broad compatibility across the most widely used quick-connect coupling systems in the UK trade market, eliminating the frustration of mismatched fittings on the workshop floor.

Manufactured from hardened steel with precision-machined tolerances, this coupling maintains a secure, vibration-resistant grip on 13mm (½" I.D.) hose — even under the cyclic pressure loads of a busy compressor system. Rated to a maximum working pressure of 35 bar (508 psi) with a flow capacity of 1,800 litres per minute at 6 bar, it will not become the bottleneck in your air system.

Key Features

• Universal multi-fit compatibility — connects with the most common quick-release coupling systems used across UK trade and industrial environments
• 13mm / ½" I.D. hose tailpiece — precision-sized for a firm, pull-resistant grip on standard bore air hose
• Hardened steel construction — resists corrosion, impact, and the mechanical wear of daily professional use
• 35 bar / 508 psi maximum working pressure — exceeds the output of virtually all workshop and industrial compressors
• 1,800 l/min flow rate at 6 bar — unrestricted airflow for high-demand pneumatic tools including impact wrenches and spray guns
• Operating temperature range: −40°C to +100°C — performs reliably from cold-start winter workshops to high-temperature industrial environments
• Quick, tool-free connection and release — reduces downtime when swapping tools or reconfiguring air lines

Technical Specifications

Specification Note

Choosing the correct hose tailpiece size is critical. The 13mm tailpiece is designed for hose with a 13mm (½") internal bore — the most common size used with ½" BSP fittings and medium-to-high flow pneumatic tools. If you are running lighter-duty tools or smaller bore hose, see our 6mm, 8mm, and 10mm tailpiece variants. For threaded connections, our BSP male thread couplings are available in ¼" and ½" BSP.
