Can you use ProPress fittings for gas?

The fittings are approved for use with natural gas, mixed gases, manufactured gases and fuel oil heating systems. ProPress G can be used to install copper gas piping as long as the gas supply contains less than 0.3 grains of hydrogen sulfide per 100-scf of gas (0.7mg/100L), per NFPA 54/ANSI Z223.

Can you use MegaPress on gas?

Viega MegaPress is the only press fitting system for black iron pipe that can be installed in both water and gas applications, residential, commercial or industrial.

What fittings are used for natural gas?

Common styles for gas fittings include adapter, coupling, cross or 4-way, 45° or 90° elbow fittings, and quick couplers.

Can you use compression fittings on gas lines?

Compression fittings in a gas piping system are not permitted unless allowed by the authority having jurisdiction. All tube fittings for natural gas installations are rated at more than 125 psig, but should not be used at pressures beyond those allowed by local codes.

Can you use ProPress for compressed air?

Viega ProPress Two-Piece Adapter Flanges Powder coating isolates the dissimilar metals, preventing electrolysis. It is a two-piece design multi-purpose adapter flange for use in general utility, potable water, chilled and hydronic heating water, vacuum and compressed air service as well as in fire protection systems.

What is the difference between MegaPress and MegaPressG?

MegaPress comes with an EPDM sealing element, while MegaPressG has an HNBR sealing element. FKM sealing elements are available in MegaPress fittings as well as MegaPress 304 or MegaPress 316 stainless fittings. MegaPress 316 is also available with an EPDM sealing element.

What is ProPress G?

The Propress G system is a copper press connection sys- tem designed to meet the demands of natural gas and liq- uid propane gas in the vapour state as well as fuel oil sys- tems. Press fittings are manufactured in copper and fittings with BSP threads connections are manufactured in bronze.

Can I use galvanized fittings for natural gas?

You do not want to use galvanized pipe for gas because of the galvanized coating. Over time pieces of the galvanized steel will flake off and clog your gas regulators and burner units. Never mix galvanized and black iron or where they touch corrosion will be accelerated.

Are brass fittings OK for natural gas?

Piping materials Steel, copper, brass: The most common gas piping is black steel. Galvanized steel, copper, brass or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper.

What do you seal gas fittings with?

When connecting gas pipelines and their fittings to a stove, grill or other connection, it is important to use Teflon tape designed for gas connections and not Teflon tape designed for water pipes. Teflon tape seals the gas fittings’ threads and keeps leaks from developing.

Are cast iron fittings used for gas?

Malleable cast­ iron fittings are used principally in piping systems with pressures of up to 300 pounds per square inch (e.g., gas .pipelines, piping systems of oil refineries, and gas and water systems of buildings). In 1976 there were eight firms producing malleable cast-iron pipe fittings.

What material is used for natural gas piping?

Polyethylene (PE) gas piping is the most widely used plastic piping material for the distribution of natural gas. PE has a well -documented inertness to both the external soil environment and to natural gas.

Can you use copper pipe for natural gas?

Please don’t use copper pipe for a gas line. It is only allowed by code under strict circumstances. Copper pipe is difficult to source, so you probably mean copper tubing. Steel piping is usually a better choice. If potential rusting is an issue, use coated steel pipe or appropriate paint to protect the pipe.

Are compression fittings OK for gas?

Compression fittings in a gas piping system are not permitted unless allowed by the authority having jurisdiction. All tube fittings for natural gas installations are rated at more than 125 psig, but should not be used at pressures beyond those allowed by local codes.
