Compression Couplings Morris Type

Bolted couplings are available in both heavy wall pipe size and tube size up to 24″Ø.

Installation requires only a 3/4″ wrench or deep socket.  Offers easy teardown and reusability.

Models available in 3, 4, 5, and 6+ bolt configurations to safely accommodate heavy wall installations.

Galvanized with plated hardware standard. All stainless available.  Various gaskets available. white nitrile, red rubber, silicone, EPDM, viton and food grade..
grade. This is the most preferred style of compression couplings. More expensive than instalok compression couplings.

Remember, slip couplings require TWO shrink sleeves to seal…

Shrink Sleeves for light Wall Systems

A heat shrinkable polyolefin band that shrinks when heated with a heat gun and wraps around the connection.  The resulting joint is mechanically strong and is vacuum tight!  A great product. Recommended for use in systems under 15 psi.

NOTE:  Based on our experience. Shrink sleeves are the least expensive method of joining light wall tubing. Use shrink sleeves with expanded end fittings for 4″Ø and less, and compression couplings with straight ends on larger sizes.

Slip couplings for light Wall Systems

Available in:Carbon Steel, Galvanized Steel, Aluminum 6061, 304 SS

Used to join any two straight ends of tube or pipe. Available with expanded ends only up to 6″.

NOTE:  Compression couplings replace slip couplings.  Slip couplings are required for joining tube ends.

Can be used for joining any two straight ends of tubing or fittings.  The slip coupling is a solid sleeve that fits the O.D. of the joint which can then be brazed, welded, or covered by a shrink sleeve. Slip couplings are used when compression couplings are not preferred.
