Unlike the hose-end couplings, these do not fit over a hose. They thread onto the discharge piping of a blast machine and present a two-lug crowfoot end for the blast hose to couple onto.\u003c\/p\u003e\n\u003cp\u003eThis is the fitting that lets you break the hose off the pot without unthreading pipe. One goes on the machine and stays there. Everything downstream of it connects and disconnects on the lugs.\u003c\/p\u003e\n\u003ch3\u003eSizes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSB1A:\u003c\/strong\u003e 1-1\/4 in female NPT, 1-1\/4 in two-lug Chicago end\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSB2A:\u003c\/strong\u003e 1-1\/2 in female NPT, 1-1\/2 in two-lug Chicago end\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine connection:\u003c\/strong\u003e female NPT, threads onto the pot discharge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose connection:\u003c\/strong\u003e two-lug crowfoot, Chicago pattern\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket:\u003c\/strong\u003e a gasket seals the lug connection.

The two-lug crowfoot ends interchange for common connections regardless of size, so a 1-1\/4 in pot coupling will still mate to a hose-end coupling on 1 in or 1-1\/4 in hose. If you are unsure what thread your machine carries, measure the female outlet or send us the make and model.\u003c\/p\u003e\n\u003ch3\u003eFitting and safety\u003c\/h3\u003e\n\u003cp\u003eThread the coupling onto the pot discharge with pipe sealant, hand tight plus a wrench pull, and check it stays tight through the first few cycles. Fit a safety cable or whip check across the lug connection between the pot and the hose. Always depressurise and bleed the pot before breaking that connection. A blast line that parts at the machine under pressure moves fast and carries abrasive with it.\u003c\/p\u003e\n\u003ch3\u003eRelated parts\u003c\/h3\u003e\n\u003cp\u003ePair with the matching aluminum two-lug hose-end coupling on the blast hose, a nozzle holder at the operator end, and blast hose in the size that suits the job. Brass versions of this pattern exist where a non-sparking fitting is required. Ask us if that is what the job calls for.\u003c\/p\u003e\n\u003cp\u003eAluminum threaded pot-end sandblast couplings, SB1A in 1-1\/4 in female NPT and SB2A in 1-1\/2 in female NPT, both with the standard two-lug crowfoot hose connection.
