SAFETY ISO NIPPLE — protected hose connections with positive retention
The Safety ISO Nipple from REAL GAZ is a hose connection designed to reduce the chance of a hose slipping off, being connected to the wrong gas or leaking under pulsing pressure.
It combines a machined brass stem with a retention profile and clearly handed thread, so a trained operator can see and feel that the joint is correct.

REAL GAZ supplies this product according to EN 560, ISO 3253 and EN ISO 5175 flashback arrestors, for site and fabrication work.
🏭 Where Safety ISO Nipples Are Used
- 🏗️ Construction sites — cutting rigs are moved daily, so retention against hose pull-off is important at every nipple;
- 🚢 Shipyards — long hose runs through hatches and decks suffer drag, which the deeper stem profile resists;
- 🛠️ Maintenance crews — mixed fuel and oxygen kits use handed threads that prevent a fuel hose being fitted to an oxygen outlet;
- 🔥 Heating and brazing — LPG and propane torches rely on firm connections near heat sources.
💡 Why Choose REAL GAZ
- ✅ Retention profile — multi-ridge serrations bite the hose without damaging the inner liner;
- 🧪 Fuel-gas compatible materials — brass and sealing parts are suited to acetylene, propane and oxygen service as specified;
- 🎯 Thread coding — handed threads and notched nuts help operators identify the gas;
- 🔒 Tested seals — each lot is pressure-tested so the joint holds at working pressure;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📐 Selection Guide
- choose left-hand thread for fuel gases and right-hand for oxygen and inert gases;
- pair the nipple with a clamp or ferrule rated for the hose pressure class;
- fit a flashback arrestor and check valve at the regulator and at the torch.
📦 Supply and Handling
Each safety ISO nipple is supplied with a matching nut and, where requested, a ferrule or crimp sleeve rated for the hose. We recommend using the same manufacturer for the hose and the sleeve, as dimensions are matched in pairs. Site teams can book a short briefing on correct assembly, including how to check a joint by hand-pull and by leak-detection fluid. Spare parts are kept in stock so that a damaged fitting can be replaced the same day it is found, which keeps cutting and welding crews working without improvised repairs.
🔬 Quality Control & Safety
- inspection of the stem profile and thread;
- pull-off testing on sample hose assemblies;
- oxygen-clean handling where specified;
- leak testing and pressure integrity checks.
Inspect every connection before use, and take any nipple with a damaged thread or seat out of service immediately. Products and cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
