A 1-1/4" Rigid 92° Connector is an angled conduit fitting intended to connect a compatible conduit run to an enclosure or other connection point while changing direction. Before ordering, confirm more than the nominal size: verify the conduit type, connection method and thread, material, installation environment, and the product’s actual dimensions. The “92°” designation describes the stated bend angle, but it does not by itself confirm compatibility with a specific installation or establish a product’s compliance with a project standard. This guide explains what to check and what information to request from a supplier.

This guide is for electrical contractors, distributors, project buyers, and OEM teams sourcing rigid conduit fittings. It is also useful when a bill of materials specifies a 1-1/4" connector but leaves important details—such as material or thread type—unclear. For projects involving aluminum pipes or conduit, confirm that the connector is intended for the relevant system rather than relying on size alone.
Requirements vary by installation and market. Treat the project specification, applicable codes, and the manufacturer’s drawing as the controlling references, and use supplier discussions to resolve missing details before placing an order.
The 1-1/4" designation is a nominal trade size; it should not automatically be treated as the fitting’s measured outside diameter. Conduit and fitting dimensions depend on the applicable product system and standard. As a unit conversion, 1-1/4 inches equals 31.75 mm, but that arithmetic conversion is not a statement that the connector’s outside diameter is 31.75 mm.
The stated angle identifies the connector’s nominal direction change. Do not assume that a 92° connector is interchangeable with a 90° fitting simply because the difference appears small. Check the drawing, installation clearance, mating components, and project requirements to determine whether the angle is acceptable.
The angle alone does not describe the connector’s overall length, internal profile, thread engagement, or clearance around an enclosure opening. Request a dimensioned drawing when those details affect routing or assembly.
Start by identifying whether the installation uses Rigid Metal Conduit (RMC), Intermediate Metal Conduit (IMC), or another conduit system. A connector that fits one system should not be assumed to fit another based only on the shared nominal size. Ask the supplier to confirm the intended conduit type and the specific end connections shown on the product drawing.
Thread type and size are critical compatibility checks. Confirm what the connector’s threaded end is designed to mate with, and compare that information with the conduit, enclosure hub, or other receiving component. If the specification does not name the thread standard, request clarification rather than guessing from a product photo or a general description.
Fittings may be offered in different materials or finishes depending on the product range, but availability and suitability must be confirmed for the specific item. For aluminum pipe or conduit projects, check material compatibility, environmental exposure, and any project requirements for corrosion protection or dissimilar-metal connections. Do not infer the connector material from the application name or the appearance of a listing image.

| Check | What to confirm | Why it matters |
|---|---|---|
| Nominal size | 1-1/4" trade size and the matching conduit system | A nominal size alone does not confirm every physical dimension. |
| Angle and profile | 92° designation, overall dimensions, and required clearance | Routing and enclosure fit depend on the actual geometry. |
| Connection | Thread type, thread dimensions, and mating component | Incorrect connections can prevent proper assembly. |
| Material and finish | Construction, finish, and suitability for the installation | These affect project acceptance and environmental suitability. |
Before requesting a quote, collect the drawing or specification, conduit type, nominal size, required angle, and connection details. Include the installation location and any stated material, finish, or compliance requirements. If the project uses a named standard or approved-product list, share its exact designation with the supplier.
Compare the supplier’s dimensioned drawing with the available space and connected components. Pay attention to the connector’s overall length, entry orientation, thread engagement, and clearance near nearby equipment. If an existing fitting is being replaced, provide clear photographs and measured dimensions, while treating those measurements as supporting information rather than a substitute for confirming the specification.
Ask for the product description, drawing, material information, packaging details, and any available compliance documentation relevant to the order. Confirm that the quoted item matches the requested size, angle, connection, and finish. Record approved substitutions in writing so purchasing, engineering, and installation teams work from the same specification.
Pricing for a connector can depend on the confirmed material, finish, order quantity, packaging, and destination. Minimum order quantities and lead times are supplier- and order-specific, so they should be requested for the exact configuration rather than assumed from a generic product listing. For project purchasing, ask whether quoted timing refers to production, dispatch, or delivery.
To make a quotation easier to evaluate, send the required quantity, destination, target schedule, packaging preference, and any drawing or compliance requirements together. If the specification allows alternatives, identify which dimensions and characteristics are fixed and which may be proposed for approval. This helps reduce quote revisions and avoids comparing products that are not technically equivalent.
A suitable supplier should be able to address the technical questions behind the purchase, not just provide a price. Ask for confirmation of the conduit system, nominal size, angle, thread connection, construction material, and available documentation. Request a drawing or written specification when fit or interchangeability is important.
At SIOSAN, we work with B2B buyers to clarify product requirements for conduit fittings and aluminum pipe-related projects. Share your specification, drawing, required quantity, and destination so we can review the requested configuration and confirm available product and order details. Where a requirement is unclear, we recommend resolving it before production or shipment rather than relying on assumptions.
A 1-1/4" Rigid 92° Connector is selected by matching its nominal size and angle to the conduit system, mating connection, installation space, and project requirements. The 1-1/4" designation is nominal, and the 92° label does not replace a drawing or compatibility check. Material, thread, dimensions, documentation, MOQ, and lead time should all be confirmed for the exact item being quoted.
Before ordering, assemble the project specification and request a written confirmation of the fitting’s system, connection, material, and dimensions. If you are sourcing from SIOSAN, send those details with your quantity and delivery location for a product review and quotation. This gives your team a clear basis for approval and helps ensure the selected connector matches the intended installation.
