coupling thread. The thread rolling cutting results in a compressive stress at the root of the 

thread, giving maximum strength to the traditional weak point of cut-thread couplings.

Our Class T coupling is using AISI 5140 to manufacture. The coupling is coated using phosphate 

chemical treatment. The couplings are available in full size, slim hole and over size.

(two) prohibit adding sealant and other fillers. Some people in order to obtain better sealing effect, in the card cover with sealant, the result of sealant is poured into the hydraulic system, causing hydraulic components, such as plugging holes. (three) when connecting the pipe, the pipe should have enough deformation allowance to avoid drawing the tube. (four) when connecting the pipeline, the lateral force should be avoided, and the lateral force will cause the seal to be too tight. (five) when connecting pipelines, should be a one-time good, avoid repeated disassembly, otherwise it will make poor sealing performance. Sleeve type pipe joint installation (1) of the pipe should need pickling pickling treatment according to the ninth chapter; (2) tube machine equipment cut tube with special cutting or sawing machine according to the required length, absolutely not allowed by fusing (such as flame cutting) or grinding wheel cutting; remove pipe end burr, metal cutting inside. Dust and dirt; remove the rust and dirt pipe joint; and also to ensure pipe roundness; (3) the sleeve nut, successively sheathed in the pipe sleeve front edge (small end) from the pipe mouth at least 3mm, then the pipe is inserted into the connector body bore, top to check; (4) slowly tighten the nut, while rotating the pipe until does not move, then tighten the nut 2/3 ~ 4/3 circle; (5) open the check card sets whether has cut the pipe correctly.

Q:Question about carbon monoxide detector ?
Welcome to the *wonderful* world of home ownership! In the almost eleven years we have lived in our current home, we have had to replace our submersible pump three times, our pressure tank once, our furnace, our water softener, our roof shingles, all of our rain gutters and downspouts. We've had to have our DWV, Schedule-40 pipe to our septic tank replaced as well as have further work done on our septic tank. We've had to tear up the carpet on the basement floors, have had our central air worked on at least three times and our new furnace worked on at least twice, as well as repairs on our built-in dishwasher. We've replaced our on-ground pool liner twice, and need to do so again, replaced our pool pump twice, and our pool fiberglas privacy panels once. We've also had to add a new 240 volt circuit for our electric range (former owners had an LP gas range), replace our brand-new refrigerator gasket (after 8eight or nine years), buy a different microwave oven and need to upgrade our circuit breaker to 200 amps. Oh, I almost forgot: we had to replace the kitchen faucets *and* the bathroom sink and faucets! The electric co. has had to replace the Security Light, the telephone co. has had to replace the service box and we still need to replace part of our inside telephone wiring! Our brand new clothes washer (bought in 1996) is tearing holes in our clothes and we've had to buy a new clothes dryer in the last nine or ten years! Have you checked your pressure tank? That's a strong possibility. Do you have a submersible or a siphon-jet well pump?
