Manufacturer’s Limited Warranty & Return Policy 

Standard Product Limited Warranty 

Subject to the limitations set forth below, BLACOH Fluid Controls, Inc. ("BLACOH") warrants its products to be free from 
defects in material and workmanship under normal use, service, and maintenance in accord with BLACOH’s published 
specifications for a period of two years from date of shipment by BLACOH (the "Warranty"). The EXCLUSIVE REMEDY for 
any product defect covered under this Warranty shall be one of the following, as determined by BLACOH in BLACOH’s sole 
discretion: (a) refund of the purchase price; or (b) replacement or repair of the defective part or parts at BLACOH’s facility. 
This Warranty will be null and void if the product is used in an inappropriate application or if the product has been altered, 
misapplied, improperly installed, or not properly inspected and maintained. To the maximum extent allowed by applicable 
law, BLACOH will not be responsible for nor have any liability for any “Damage,” which means any of the following, whether 
the claim sounds in breach of contract, breach of warranty, tort, strict liability, implied contractual indemnity, or otherwise: (i) 
any damage, loss, or injury of any kind, or destruction, or death, whether or not caused by any defect in a BLACOH product 
and whether or not the BLACOH product is installed, used, operated, and/or maintained in accord with BLACOH instructions, 
to other products, machinery, buildings, property, or persons, and (ii) any costs, expenses, losses, or incidental, 
consequential, or special damages of any kind or nature, including but not limited to loss of profits, arising from or related to 
any BLACOH product, whether or not caused by any defect in a BLACOH product and whether or not the BLACOH product 
is installed, used, operated, and/or maintained in accord with BLACOH instructions. Damage resulting from chemical 
incompatibility or from over-pressurization of a product, whether from gas or fluid, is not covered under this Warranty, nor will 
BLACOH be responsible in any way for any such Damage. Because BLACOH does not determine and cannot anticipate or 
control the many different conditions under which its products may be used, BLACOH does not warranty the applicability, 
suitability, or fitness of any of its products for any particular use or purpose. Statements concerning the possible use of 
BLACOH products are not intended and shall not be interpreted as warranties of fitness for any specific use of such 
products. Each user of BLACOH products must conduct its own engineering analysis and tests to determine the suitability of 
each BLACOH product for the user's intended uses or purposes, including but not limited to chemical compatibility and 
pressurization, and any written or oral assistance from BLACOH in this regard does not relieve the user from exclusive 
responsibility for such engineering analysis and testing. BLACOH products are sold with only this limited Warranty, and each 
buyer assumes all responsibility for Damage (as defined above), including but not limited to, Damage arising from defects in 
BLACOH products and/or from the handling and use of BLACOH products whether used in accordance with BLACOH's 
directions or otherwise. Any products sold by BLACOH which are manufactured by and sold under the name of another 
company are NOT WARRANTED by BLACOH under the foregoing Warranty or otherwise. The buyer must rely exclusively 
on the product warranty, if any, given by such other company. Products manufactured by BLACOH as an original equipment 
manufacturer (OEM) to be sold by a customer under the customer’s brand and name are warranted by BLACOH only under 
the above Warranty, and BLACOH shall have no liability whatsoever with respect to any representation or warranty given by 
such customer (or such customer’s representatives, distributors, agents, employees, or independent contractors) to any of its 
buyers which is different in any respect whatsoever from the foregoing Warranty. EXCEPT FOR THE WARRANTY GIVEN 
ABOVE, WHICH IS SUBJECT TO THE ADDITIONAL LIMITATIONS STATED ABOVE, AND EXCEPT FOR THE 
ADDITIONAL LIMITED WARRANTY ON BLACOH’S PTFE BELLOWS STATED BELOW, BLACOH GIVES NO WARRANTY 
OF ANY NATURE WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO ANY OF ITS PRODUCTS, INCLUDING 
WITHOUT LIMITATION NO WARRANTY OF MERCHANTABILITY AND NO WARRANTY OF FITNESS FOR A 
PARTICULAR PURPOSE. NO COURSE OF DEALING, USAGE OF TRADE, OR OTHER ORAL OR WRITTEN 
STATEMENTS SHALL MODIFY THE FOREGOING WARRANTY PROVISIONS AND LIMITATIONS IN ANY RESPECT 
WHATSOEVER. This Warranty shall be governed by and construed in accordance with the laws of the State of California. 

PTFE Bellows Limited Warranty 

In addition to BLACOH's Standard Product Limited Warranty and subject to the limitations set forth below, BLACOH warrants 
that its PTFE Bellows equipment (“PTFE Bellows”) on BLACOH's PTFE Bellows-fitted pulsation dampener will perform in 
accordance with BLACOH's written product description for three years from date of shipment ("PTFE Bellows Warranty"). 
This PTFE Bellows Warranty applies only to PTFE Bellows that are sized, charged, installed, used, operated, and 
maintained strictly in accordance with all installation, use, operation, and maintenance instructions provided by BLACOH, 
and failure to properly size, charge, install, use, operate, and maintain the PTFE Bellows (or failure to do any of them) shall 
make the PTFE Bellows Warranty null and void. This PTFE Bellows Warranty does not include applications where failure of 
performance is due to an unbalanced pressure load or a transient pressure spike (sometimes called a water hammer). The 
EXCLUSIVE REMEDY for breach of this PTFE Bellows Warranty is replacement of the PTFE Bellows at BLACOH’s facility, 
and not any other equipment or parts whatsoever, and BLACOH will not be responsible for any Damage or any other loss of 
any kind, including but not limited to incidental, consequential, or special damages (including but not limited to loss of 
profits), in any way arising from failure of the PTFE Bellows to perform in accordance with BLACOH’s written product 
description. This PTFE Bellows Warranty shall be governed and construed in accordance with the laws of the State of 
California.
