3/8 inch male coupler with 3/8 inch female plug assembly from Dynabrade is an air line fitting set designed to join air tool lines using matched components. The coupler uses a 3/8 inch male NPT thread, which connects directly into a 3/8 inch NPT tapped air line or manifold, so installers can tie this fitting into existing hard lines or hose ends using that standard pipe thread. The plug uses a 3/8 inch female NPT thread, which lets it thread onto 3/8 inch NPT external fittings on hoses or tools, keeping everything on one common pipe thread standard. This assembly is rated for up to 74 SCFM air flow, so it supports substantial air volume for tools within that range while limiting restriction in the line. Dynabrade specifies to only use Dynabrade couplers with Dynabrade plugs, which keeps sealing and engagement matched to the manufacturer design.
This Dynabrade 3/8 inch male coupler with 3/8 inch female plug assembly uses NPT threading on both pieces, so it ties directly into standard tapered pipe-thread air systems. The coupler side uses a 3/8 inch male NPT thread, letting it screw into 3/8 inch NPT ports on manifolds, regulators, or hose ends in a compressed air run. The plug side uses a 3/8 inch female NPT thread, so it can attach to a 3/8 inch NPT male thread on a hose or tool inlet while keeping the connection within one fitting family. Because the assembly is specified as an air line fitting and rated up to 74 SCFM air flow, it is suited to handling the connection point in lines that serve air tools operating within that flow range.
The Dynabrade 98268 3/8 inch male coupler with 3/8 inch female plug assembly fits into compressed air systems that use 3/8 inch NPT threading throughout the line. The coupler, with its 3/8 inch male NPT thread, is positioned where a male-threaded connection is needed into a 3/8 inch NPT port on a manifold, outlet block, or hose end. The plug, with its 3/8 inch female NPT thread, is suited to threading over 3/8 inch NPT male ends on hoses or tools, keeping that side of the connection on the same pipe-thread standard. Because it is classified under Air Line Components and Air Line Fittings, this assembly serves strictly as a connecting interface in the air path, placing it in the part of the system where hoses and tools are joined to the supply line.
The matched 3/8 inch male NPT and 3/8 inch female NPT threads on this assembly give installers a clear pattern for how each side of the fitting is used, which supports consistent connection layouts across multiple drops or tools. The up to 74 SCFM air flow rating defines the air volume the assembly is designed to handle, helping users keep air tool demands aligned with the fitting capability so the connection point does not become the limiting section in the line. The supplier note to only use Dynabrade couplers with Dynabrade plugs keeps both pieces in the same design family, which maintains the intended interface between the coupler and plug when they are paired. The specific Dynabrade branding and part number 98268 provide a clear identifier when matching or repeating installations, so shops can duplicate an air line fitting configuration by calling out this exact assembly for additional drops or tool stations.
The coupler uses a 3/8 inch male NPT thread, which lets it screw directly into 3/8 inch NPT tapped ports on air manifolds, regulators, or hose ends built around that pipe-thread size.
The plug uses a 3/8 inch female NPT thread, so it threads onto 3/8 inch NPT male fittings on hoses or tools, keeping both sides of the connection on standard pipe threads.
The Dynabrade 98268 coupler and plug assembly is rated for up to 74 SCFM air flow, supporting tool and system demands that fall within that flow range at the connection point.
This product is classified as an Air Line Component and Air Line Fitting, so it is designed for use in compressed air systems rather than fluid or gas lines outside that role.
The manufacturer specifies to only use Dynabrade couplers with Dynabrade plugs, which keeps the mating components within one design family for interface consistency.
This assembly is identified as the Dynabrade 3/8 inch male coupler with 3/8 inch female plug, manufacturer part number 98268, which provides a precise reference for repeat purchases.
The Dynabrade 3/8 inch male coupler with 3/8 inch female plug assembly suits air line layouts built around 3/8 inch NPT connections and tools running within a 74 SCFM flow range. By using a coupler with a 3/8 inch male NPT thread and a plug with a 3/8 inch female NPT thread, the assembly keeps both sides aligned to common air system pipe threads. For shops standardizing on Dynabrade air line fittings, the clear 98268 identifier and the guidance to use Dynabrade couplers with Dynabrade plugs support consistent setups across multiple tool stations.
