Braided Bellows Offer:
The addition of braid to our standard bellows provides all the features of standard bellows plus the following added benefits:
• Dampens vibration
• External protection
• Prevents hose elongation under pressure (consult factory with pressure requirements)
Braid can be attached to bellows ID or OD

Braided Formed Bellows offer:
• For non-torsional applications
• The ideal solution for a no-leak decoupler that will accommodate all four motions
• Pre-formed braid offers thermal properties
• 63% heat loss reduction
• Excellent compression and extension movement

H-P Products' certified weld inspectors insure your parts requiring welded bellows meet the requirements of your part.
In addition we offer heat wrap solutions for parts requiring the bellows to be insulated.

Our customers require H-P Products to ship entire tube assemblies to increase their throughput and reduce their assembly time and costs.

H-P Products is now offering replaceable bellows designs in complete part assemblies. Bellows typically have a five to six year lifecycle so why not incorporate a replaceable bellows design in your next Tier 4 part design. When the bellows fails it can quickly and easily be replaced in the field.
