How does the Oxyset compare to oxy-acetylene brazing?

The Oxyset (1811167-2) can be used to braze copper pipes up to 1.5″ (38mm) in diameter. Whilst oxy-acetylene produces a higher flame temperature, oxy-map produces a high flame temperature suitable for many brazing applications. Due to its compact size and weight, the Oxyset is an ideal companion for plumbers, gas-fitters and HVAC technicians.

How long does the Oxyset Oxygen Cylinder run for?

As the highest-pressure disposable cylinder in the market, Bromic 1L Oxygen Disposable Cylinder provides more gas in a compact cylinder. When used with the Oxyset tip #1 and Map//Pro gas, the Bromic 1L Oxygen Disposable Cylinder allows roughly 45 minutes of run time. Actual consumption rates may differ depending on the user and settings.

The OXYSET (1811167-2) is fuelled by a disposable oxygen cylinder (T-PED approval number 0036) and
a disposable MAP//Pro cylinder (complying with DOT39). We recommend using Bromic oxygen
cylinders (P/N 1811320) and BernzOmatic MAP//Pro cylinders (P/N 1811120).

What’s the difference between Loxeal 58-11 and 18-10 Thread Sealant?

Whilst Loxeal 18-10 is designed for medium-pressure gas applications, Loxeal 58-11 is designed for high-pressure gas and water applications.

What’s the difference between a thread-sealing compound (thread pastes) and an anaerobic thread sealant?

Thread-sealing compounds are usually solvent-based and work by hardening as the solvent evaporates. As solvent-based thread-sealing compounds present a risk of shrinking and cracking over time, they are best for sealing threads in maintenance applications where a permanent rigid bond is not essential.

Anaerobic thread sealants are high-performance sealants that only cure when oxygen is expelled. Anaerobic thread sealants such as Loxeal 58-11 are ideal for sealing permanent fixtures in commercial applications.

Which thread sealant can be used on Natural Gas and LPG (propane) pipes?

SUPA-SEAL P.T.F.E Thread Seal Tapes, Loxeal Thread Sealants and LA-CO T-O-T and Slic-tite® Thread Sealing Compound can be used to seal pipes containing Natural Gas or LPG (propane).

When should I use a liquid thread sealant or thread sealing compound instead of thread seal tape?

A liquid thread sealant or thread-sealing compound is recommended when sealing larger-diameter pipelines. For high-strength sealing on permanent structures, it’s important to use a high-performance thread sealant such as the Loxeal®58-11. The Loxeal®58-11 is not only AGA-approved for use with gas, it is also WaterMark-approved for use with potable water.

What’s the difference between a manual changeover and an automatic changeover gas regulator?

Manual changeover and automatic changeover dual-stage gas regulators are used for multi-LPG cylinder setups.

Once one LPG cylinder runs out, an automatic changeover regulator will automatically switch from using one gas cylinder to another. For manual changeover regulators, the user will need to manually reset the valve after the first gas cylinder runs out.

Manual Changeover Gas Regulators

  • PRO: Less likely to end up with two empty gas cylinders
  • CON: Have to pause gas usage to manually go outside to switch the gas cylinder

Automatic Changeover Gas Regulators

  • PRO: Switches cylinder when 1 runs out, without having to pause gas usage
  • CON: Need to routinely inspect the gas regular indicator to ensure the gas bottles are not empty. This must be done up to every month, depending on gas usage

To suit your preferences, Bromic supplies both automatic and manual changeover gas regulators.

Can Bromic, Kosan or Cavagna gas regulators be used indoors?

Only our appliance regulators are for indoor use. All other gas regulators are for outdoor use only.

What are First Stage and Second Stage gas regulators used for?

First Stage and Second Stage gas regulators are used in domestic and commercial applications.

A first stage gas regulator is often connected to one or two gas cylinder/s with pigtail/s, taking the pressure from max. 1750kPa to approximately 70kPa. A second stage gas regulator is placed further along the gas line and takes the gas pressure from approximately 70kPa to 2.75kPa.

We recommend Kosan First Stage and Second Stage regulators for high-pressure and high-volume commercial applications.

What does the safety shut-off feature do on dual-stage regulators?

All Bromic and Cavagna dual-stage regulators comes with a patented safety shut-off feature.

The safety shut-off is a mechanism that will engage in the event of gas flow greater than 140% of rated flow (e.g. regulator diaphragm failure, equipment leakage downstream). This prevents any potential disasters and ensures safety at all times.
