Available Clamps
Hanna Rubber Company offers four different types of band clamps K Series Clamps, F Series Clamps, Smooth ID Clamps, and Smooth ID Center Punch Clamps. All of out clamps are offered in either stainless or galvanized steel. The F Series Clamps can come either preformed or open end.
Smooth ID Clamps are ideal for softer rubber products to prevent the clamp from damaging the hose. Our center punch smooth ID clamps are double wrapped and suggested when used in applications where conditions are highly corrosive.
Some of our band clamp products may require specialty tools to use the product properly.
F Series Band Clamps
Features:
- Install with center punch tools
- On stainless clamps, bands are 300 series stainless steel
- Buckles are 302 series stainless steel
- double-wrapped
- triple-punched
- holds permanently
K Series Band Clamps
Features:
- On stainless clamps, bands are 300 series stainless steel
- Buckles are 302 series stainless steel
- Designed to be slipped over the hose end before the fitting is inserted
- Can be center punched or rolled over
- Install with the center punch or roll over tools
Smooth ID Band Clamps
Features:
- provides a uniform, gap-free inside diameter, and strong holding power
- Install with roll over type clamp tools and most common band clamp tools
Smooth ID Center Punch Band Clamps
Features:
- Double wrapped and locked with the conical punch
- Unique dimple design offers excellent sealing strength while maintaining radial compression
- Heavy buckle provides optimal holding power
- Ideal for thin wall hose
- Low profile
Hanna Rubber’s bolt clamps are made from plated ductile iron. The smaller sizes are popular for hydraulic suction lines, while larger clamps are often used for irrigation and general suction and discharge service.
Double Bolt Clamps
Features:
- Inner surface has dual gripping ridges
- Bolts lugs are reinforced to prevent bending out of alignment
- Measure hose OD accurately before ordering clamps
- Torque values for clamps are based on dry bolts. The use of lubricant on bolts will adversely affect clamp performance
- Consult Hanna Rubber when using double bolt clamps on helical wire hose
Single Bolt Clamps
Features:
- Measure hose OD accurately before ordering clamps
- Torque values for clamps are based on dry bolts
- The use of lubrication on bolts will adversely effect clamp performance
We offer our ear clamps in both zinc plated steel and stainless steel bands. Ear clamps are placed over the end of the connecting hose and once the ears of the band have been pinched the band will tighten around the hose creating a secure fit. When selecting an ear clamp size make sure to get it only slightly larger than the size of the hose to ensure you will have a secure fit.
Our stepless ear clamps hold against pressure and vibration or material shrinkage due to temperature change or aging. A built in spring allows the clamp to “breath” without loosening. Just like the pinch-on ear clamps the stepless ear clamp must be pinched to ensure a proper seal.
Pinch-On Double Ear Clamps
Features:
- Band width: .275″
- Band thickness: .030″
When ordering pinch-on double ear clamps, select nominal clamp size nearest to, but always larger than, the OD of material to be clamped after insert has been fitted.
Stepless Ear Clamps
Features:
- Ensured clamping seal
- For low durometer and/or thin-walled hose/tubing
- For silicon, vinyl, polyurethane or other high-tech materials
- Smooth inner band prevents damage to the hose while the tongue-in-groove design provides a 360° seal
- No steps or gaps inside the clamp
- Stepless ear clamps hold against pressure and vibration or material shrinkage due to temperature changes or aging.
- A built-in spring action permits the clamp to breathe without loosening.
Spiral Clamps
Features:
- More than one clamp may be needed per size, contact us for more information
- Due to fluctuations in the OD of hose each individual installation should be checked
- For use on convoluted cover hose
Worm gear clamps consist of a band that has a special punch cut into the band into which a screw uses that pattern to tighten and loosen the clamp. The clamp is put around the hose or tube to be connected, with the loose end being fed into a narrow space between the band and the captive screw. When the screw is turned, it acts as a worm drive pulling the threads of the band, causing the band to tighten around the hose.
Aero-Seal Clamps
Features:
- Four-piece construction
- Band slots designed for strength and smooth action
- Saddle interlocks into embossed band to form a true concentric circle
- Slotted hex head screw design
- Heat treated screws have buttress thread type
- Maximum recommended torque 50 in. lbs.
Torque ratings correspond to the torque rating of the screw of the clamp and are not an
indication of the working pressure of any hose assembly installed with this clamp.
