Raceway systems such as EMT and rigid conduit are permitted by most codes to be embedded in concrete. The solid exterior of these conduits eliminates the possibility of concrete entrance, however, the termination with the connector or coupling can be susceptible to concrete entering the raceway.

The UL 514B testing procedure requires the connector or coupling to be assembled to the conduit inside a special concrete form. Then Portland-type concrete is poured into the form and over test samples. Then the concrete slurry is vibrated to remove any trapped air, and allowed to cure. After concrete curing, the fittings are chipped out of the concrete and examined for concrete penetration.
Although compression style connectors and couplings pass these tests in all trade sizes because of the gland ring design, the set screw types may have difficulty conforming to UL or CSA concrete penetration requirements. When the set screw is tightened onto the conduit, the fitting and/or conduit material will 'yield', or stretch, enough to create an opening at the conduit/ fitting connection.
Set screw fittings in the smaller (1/2', 3/4', and 1') trade sizes are less likely to stretch to the point that would permit entrance of concrete. However, 1-1/4' and larger size fittings will yield enough so that concrete can enter the raceway. UL and CSA will accept product carton marking that specify 'Concrete-Tight When Taped' on fittings that cannot pass testing, since the tape prevents entrance of concrete into the raceway. The taped joint must completely encircle the conduit/ fitting connection. We recommend using duct tape or similar type of durable tape.
In the world of hydraulic fittings and adapters, there are a variety of questions we often get asked, from both our customers and those just interested in learning more. At Air-Way Global Manufacturing, we pride ourselves on providing clear, concise answers to our customers' most pressing inquiries.
In this blog, we'll dive into the top five questions we're frequently asked, providing the insights and information you need.
Many times, it is straightforward, and we can identify with a simple description, and measurements. Other times, we may request a photo, or more detailed measurements.
Where it can become tricky is when we are asked for a British Standard Parallel Pipe (BSPP) end. There are several specifications that include these threads, such as BS, JIS, and ISO . These fittings are not interchangeable and require confirmed identification before we can confidently identify the type of fitting you need.
The rated working pressure for any fitting is based on the lowest pressure-rated fitting end. For example, a fitting may include one -4 (1/4") male 37-degree tube end and one -6 (3/8") male pipe end.
For more overhead line fittings suppliersinformation, please contact us. We will provide professional answers.
From the tables here, the rated working pressure for the -4 male 37-degree tube end is 34.5 MPa (5,000 psi) and the rated working pressure of the -6 (3/8") male pipe end is 21 MPa (3,000 psi).
Therefore, the rated working pressure of the fitting would be 21 MPa (3,000 psi). Please keep in mind, however, that pressure ratings for steel tubing differ.
This depends on what the part is and if we have it in stock. However, our engineers are always available to discuss custom projects and applications and can provide CAD drawings, models, and more for custom parts.
In fact, we can usually ship out standard parts within 1 business day and finish custom designs quickly if necessary!
O-Rings are considered a universal sealing device. However, if you noticed that your part didn't come with an O-Ring, it's because your print or part number simply did not call for one.
The O-Ring Face Seal (ORFS) style fitting is designed for higher pressure fluid power applications and provides a connection between steel tubing and SAE J / ISO -1 O-Ring Ports. The Style B, Dovetail Groove design aids in O-Ring retention.
While shipping and delivery times vary based on a variety of factors, Air-Way Global Manufacturing prides itself on providing some of the quickest and most efficient shipping times in the industry.
Many times, we can ship out your part within 1-2 business days of ordering and also have the capability to finish custom designs quicker than most.
