Low-Pressure Stainless Steel Unthreaded Pipe Flanges
Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a
Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides. Stub-end flanges are also known as lap-joint flanges; use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting. Cap flanges are also known as blind flanges.
Forged flanges have better strength than cast flanges. Cast flanges are also called MSS flanges.
304 stainless steel flanges offer very good corrosion resistance. 316 stainless steel flanges have excellent corrosion resistance.

High-Pressure Stainless Steel Unthreaded Pipe Flanges
Use these heavy duty forged flanges for high-pressure applications. Bolt two flat-surface flanges or two raised-surface flanges of same size together with a gasket (sold separately) to create an access point in a pipe line.
304 stainless steel flanges offer very good corrosion resistance. 316 stainless steel flanges have excellent corrosion resistance.
Stub-end flanges are also known as lap-joint flanges; use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting.

High-Pressure Stainless Steel Unthreaded SAE Pipe Flanges
Create an access point in a high-pressure hydraulic fluid line with these flanges. They are also known as Code 61 SAE hydraulic flanges. To connect, bolt a flange with an O-ring groove surface to a flange with a flat surface of the same size. Flanges are 316 stainless steel for excellent corrosion resistance.
Socket-connect flanges weld to pipe for a strong, permanent connection. Cap flanges are also known as blind flanges.

High-Pressure Stainless Steel Threaded SAE Pipe Flanges
Also known as Code 61 SAE hydraulic flanges, these let you create an access point in a high-pressure hydraulic line. To connect, bolt flanges to equipment, or bolt a flange with an O-ring groove surface to a flange with a flat surface of the same size. Flanges are 316 stainless steel for excellent corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
- Specifications Met: SAE J518, ISO 6162
- For Use With: Hydraulic Fluid

Minimal-Spill Push-and-Turn Hose Couplings for Chemicals
Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line. Tough enough to handle frequent use, these couplings are designed to be virtually spill free. Also known as dry disconnects and double-shut off couplings, both the plug and the socket have a shut-off valve that stops the flow of liquids when they’re separated. To connect, push the plug into the socket and lock with a quarter turn. The socket swivels, so you won’t have to twist your hose to attach the plug. It also has a rubber lip and large handles to prevent damage if it’s dropped.
A complete coupling consists of a plug and a socket (both sold separately). They’re compatible with MannTek, Avery Hardoll, Todo-matic, and other dry-disconnect couplings that meet NATO standard STANAG 3756.
Aluminum couplings are lighter in weight than stainless steel and have good corrosion resistance.
