Dimensions and Pressure Ratings
People often ask about the pressure rating of a fitting, when it is actually the clamp that would "pop" before a stainless steel fitting would burst. All sizes below are for Tube OD. PSI service ratings are based on tests using Buna-N gaskets. All ratings shown are dependent upon related components in the system and proper installation.
| Sizes Available |
13MHLA
Simple toggle action for installations requiring frequent quick opening and closing. Adjustment screw compensates for gasket yield. |
1 to 4" |
13MHHM
Our most commonly used style. Heavy construction provides protection against leakage or misalignment. Held in position by hand tightened wing nut. |
1 to 8" |
13MHHS
Patented heavy duty, three-segment (TC-3) design has stop hinges to promote easy, fast alignment and speed installation. |
1 to 4" |
13MHP
Two-piece high pressure clamp uses stainless steel bolts and heavy cast construction. |
1.5 to 6" |
13MO Type 1
Lightweight stainless steel clamp offers quick positive coupleing action. Tee bolt locks into latch. |
1 to 6" |
13MO Type 2
Same design and Type 1 but has two mating components to equalize load over larger circumference. |
8 to 12" |
NOTE: 1" fittings take 1.5" clamp assemblies
