Flexible expansion and contraction anti-detachment joint SKX (10-50mm)(81)
The SKX flexible expansion joint (10-50mm) is a connector that allows for easy connection of different types of pipes. No pre-treatment such as chamfering, core insertion, gluing, threading, polishing, or coating removal is required; simply insert the pipe and tighten to connect. It is also easy to separate the pipe and joint by just loosening the bolt, nut, and cap. (An open tool is required for polyethylene pipes.)

MESCO-made mechanical seismic joint for pipes, Suppon MW joint(3)
The Suppon MW joint is a seismic joint designed for pipes, manufactured by Mitsui Metal Engineering Co., Ltd. (MESCO), that does not require disassembly. It is compatible with nominal diameters ranging from Φ40 to Φ200. The allowable water pressure can be supported up to 2.0 MPa by using a dedicated in-core.

Soft-shelled turtle MI joint(1)
We would like to introduce our non-dismantling mechanical joint for cast iron pipes, the "Suppon MI Joint."

SKX medium caliber (65-100mm)(4)
The SKX medium diameter flexible expansion joint (65-100mm) is a connector that allows for easy connection of different types of pipes. No pre-treatment such as beveling, core insertion, gluing, threading, polishing, or coating removal is required; you simply insert the pipe and tighten it (no torque management needed) to make the connection. Separation of the pipe and joint can be easily done by loosening just the bolt, nut, and cap. (An open tool is required for polyethylene pipes.)
-
PVC and steel pipe M joint for suction.(2)
The Suppon M Joint is a mechanical joint that does not require disassembly or lubrication. The wide anti-disengagement fitting (stop ring) does not leave deep scratches on the pipe, and reinstallation is easy by simply loosening the bolt and nut. The flexible stop ring can absorb the expansion and contraction of the pipe due to temperature differences and distortions caused by external forces. Furthermore, since the stop ring is independent of the pressing ring, the disengagement force does not act on the pressing ring, ensuring that water tightness is not compromised.
-
M Joint for Poly Pipe (JIS) and SUS Pipe(6)
The M joint for poly pipes (JIS) and SUS pipes is a mechanical joint that does not require disassembly. An in-core is not necessary for connecting polyethylene pipes (JIS standard products). It can also be used for connecting different types of pipes, such as PVC and steel pipes.
-
Large Diameter Suction M Joint (350–500mm)(6)
The large-diameter suction M joint (350–500mm) is a mechanical joint that does not require disassembly or lubrication. The wide anti-disengagement fitting (stop ring) does not leave deep scratches on the pipe, and reinstallation is easy by simply loosening the bolt and nut. The flexible stop ring can absorb the expansion and contraction of the pipe due to temperature differences and distortions caused by external forces. Furthermore, since the stop ring is independent of the pressing ring, the disengagement force does not act on the pressing ring, ensuring water tightness is not compromised.

Ducktape cast iron pipe (DCIP) spigot MD joint(5)
The MD joint for ductile cast iron pipes (DCIP) is a mechanical seismic joint that does not require disassembly or lubricants. It has fewer tightening bolts, which shortens construction time. Additionally, the pipe and fitting can be separated simply by loosening the bolts and nuts, making reinstallation easy. The flexible anti-disengagement fittings (stop rings) absorb pipe distortion caused by earthquakes due to the allowance for disengagement length and the synergistic effect of adjacent joints, maintaining sufficient seismic performance even against seismic motion level 2 (90% non-exceedance probability, assuming soft ground).
-
MD joint for inner and outer coated steel pipes (PD and VD steel pipes)(27)
The MD joint for internally and externally coated steel pipes (PD and VD pipes) is a mechanical joint that does not require disassembly. It can be connected simply by inserting the pipe and tightening the bolt and nut, with no need for pre-treatment such as threading or coating removal.

Suction MP joint for polyethylene pipes used in water distribution (JW-P)(8)
The MP joint for polyethylene pipes used in water distribution (JW-P) is the industry's first seismic-resistant mechanical joint that does not require an in-core or disassembly. It has a seismic resistance with an allowable strain of over 4% (for diameters of 50 to 150 mm) without an in-core, making it a sufficiently safe joint against anticipated seismic movements. No special tools or dedicated equipment are needed; it can be tightened with just one wrench, allowing for installation that is not affected by the work environment or weather conditions. Additionally, by loosening the bolt and nut and using an open nut, the separation of the pipe and joint can be easily accomplished.
