ProCoat is applied to the corrugated stainless steel connector using advanced powder-coat technology. The proprietary polymer coating is designed to withstand prolonged exposure to harsh household chemicals, UV rays and salt. If the holes are of any cosmetic concern the property owner can have them painted with a matching paint.BrassCraft’s ProCoat stainless steel gas connector is engineered with added safety in mind. We will make every effort to use a caulk that closely matches the color of the surrounding siding however in some cases the holes may be noticeable upon close inspection. These holes will be filled with caulk when the testing is completed. 3/16” holes will be placed under most windows and other possible moisture entry areas.

We use standard industry practices for conducting the moisture tests, which includes the use of a penetrating probe meter to verify the moisture content of the structural wood and sheathing of the building. Any security systems will need to be shut off during the testing, which can take several hours. We should have access to all parts of the exterior. In order to perform this inspection, we need the permission of the owner. A moisture inspection of your property has been requested. Structure Tech specializes in the moisture testing of buildings for the purpose of determining if there is moisture located behind the exterior wall cladding. We cannot perform the moisture testing requested by the buyers without this form being signed. This form must be completed and signed prior to us conducting any moisture testing. CSST is a relatively new type of gas piping that looks similar, but it’s not an appliance connector.Īuthor: Reuben Saltzman, Structure Tech Home Inspections Oh, and one other thing – don’t confuse gas connectors with Corrugated Stainless Steel Tubing (CSST). When a gas appliance is replaced, the connector should be replaced at the same time. Gas appliance connectors should never be reused. Click the following link for Bloomington’s position on old gas connectors.Īlso, the Minnesota code standards for gas appliance connectors can be found in the Minnesota State Fuel Gas Code under section 411.1.3.ĭon’t reuse gas connectors. The Truth-In-Sale of Housing programs for Minneapolis, Bloomington, and several other cities require replacement of these old connectors. The older gas connectors are much more prone to leakage, making them a latent hazard. If a gas connector doesn’t meet this standard, it should be replaced. To know for sure, you can look closely at the nut, or sometimes at a ring that has been attached to the connector. If the connector has a grey coating or is made from uncoated brass, it’s old. Newer connectors are typically coated with yellow, like the one shown at the beginning of this blog, or will be plain stainless steel, like the one pictured at the bottom of the photo below. Old connectors will typically have a grey coating, like the one shown above left, a braided stainless steel jacket like the type shown below, or they’ll obviously be made of uncoated brass like the one shown far below. To quickly spot the difference between the old and new connectors, you can usually just look at the outside jacket.

The old connector obviously isn’t it’s made from brass, or so I’ve been told. The new gas connector, which complies with ASNI Z21.24, is made from stainless steel. Here’s what I found.Īs you can see, they’re made from different materials. I got my hands on a new gas connector and an old one, and I cut ’em open. I tried to get a copy of those standards so I could say what makes the newer connectors different, but it would have cost me $336 (get out of here), so I did something more interesting. The current standard for gas appliance connectors is ANSI Z21.24. Only proper gas piping should be run through walls, floors, cabinets, etc. If a gas connector disappears into a wall, floor, ceiling, or cabinet of an appliance, it’s an improper installation. Gas Connectors should never disappear into a concealed location. This material is not a flexible gas line. This means that if you ever see two connectors joined together, it’s an improper installation. Gas connectors should never be used as a substitute for gas piping. A gas connector is used to get from the gas piping to the appliance, and that’s all.

Most newer gas connectors look just like this one. To start, here’s a photo of a gas connector it’s that corrugated yellow thingy. Gas Connectors are not a substitute for gas piping. I’ll cover the most common installation defects, and I’ll go over the differences between new and old connectors. Today I’ll discuss the stuff that I look for while inspecting gas appliance connectors. Gas appliance connectors are devices that connect gas appliances to gas piping, kind of like a cord connects an electrical appliance to an outlet at the wall. Gas appliance connectors aren’t the same as gas piping.
