2.   WARRANTY. SELLER warrants that any product of its manufacture, which upon examination is found by a SELLER’S representative to be defective in either workmanship or material under normal use and service, will be, at SELLER’S option, repaired or replaced free of charge including lowest transportation charges but not cost of installation or removal, or have the purchase price refunded, provided that SELLER receives a written claim specifying the defect within ninety (90) days from date of distributor sale or one (1) year from date of factory shipment, whichever occurs first. In no event shall SELLER be liable for any claims, whether arising from breach of contract or warranty or claims of negligence or negligent manufacture, in excess of the purchase price. ALL OTHER WARRANTIES EXPRESSED OR IMPLIED INCLUDING ANY WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR USE ARE HEREBY DISCLAIMED. The foregoing expresses all of SELLER’S obligations and liabilities with respect to the quality of items furnished by it, and it shall under no circumstances be liable for claims for indirect, consequential, collateral, or special losses or damages.
      a. All orders received from BUYER are subject to acceptance by SELLER, unless quotation specifies that it is a bid in response to an invitation for bids in which event the order or award shall constitute acceptance of the bid in accordance with the bid terms.
      b. Terms and conditions on the BUYER’S order form, at variance with terms and conditions stated herein, are binding upon SELLER only if specifically accepted by SELLER in writing. Absent such written acceptance, these terms and conditions shall apply to all sales of SELLER’S products.
      c. Orders accepted by SELLER cannot be cancelled by BUYER except with SELLER’S written consent and upon terms that will indemnify SELLER against loss or otherwise compensate SELLER for all costs of performance incurred by SELLER through cancellation.
      a. Unless otherwise stated, legal delivery and prices are Ex Works SELLER’S plant, and prices may not include transportation charges.

      b. Taxes Not Included in Price: Except where otherwise prohibited by law, all sales, excise, use or similar taxes or charges by the federal, any foreign, or any state or local government, which SELLER may be required to pay or collect, shall be in addition to price stated and shall be paid by BUYER, unless a valid exemption certificate is furnished therefore.
      c. Payment: All accounts are payable within terms stated on SELLER’S invoice. SELLER may demand payment or Irrevocable Letter of Credit (L.O.C.) in advance of shipment if, in SELLER’S opinion, the credit or financial condition of BUYER is, or is about to become, impaired; or SELLER has insufficient credit history with BUYER.
      d. Payments Where Shipments are Delayed: In the event of BUYER caused shipment delays, e.g. where BUYER requests delay in shipment or BUYER does not perform inspection BUYER requires before shipment, SELLER shall have the option of billing for goods when ready for shipment. If material is not ordered out within sixty (60) days after goods are ready, SELLER will have the option of billing storage charges.
      e. Prices subject to change without notice.
      a. Shipping Dates: Shipping dates are approximate only and are subject to change.
      b. Unforeseen Delays: SELLER shall not be liable in damages or otherwise for delays or failure in performance when caused by circumstances, of every nature and description and however arising, beyond SELLER’S reasonable control. In the event that SELLER is unable, due to any such occurrence or otherwise, to fulfill its total commitments to all customers, BUYER agrees to accept as full and complete performance by SELLER, deliveries in accordance with such plan or proration as SELLER may adopt.
      c. Packaging: SELLER will provide commercial packaging, adequate under normal conditions, to protect the goods in shipment and identify the contents. Should BUYER request any special packaging, it will be done at BUYER’S expense.
      d. Routing: All goods will be shipped via the most cost effective means of transportation under the circumstances, unless BUYER indicates otherwise. In the event BUYER requests expedited shipping and handling, SELLER shall comply provided BUYER pays all reasonable expediting and increased shipping fees and expenses. If BUYER provides no routing instructions, SELLER shall be the sole judge of the best method of routing shipment.
      e. Claims: Claims for loss or damage in transit must be entered and prosecuted by the BUYER. SELLER will provide reasonable assistance upon request.
6.   INSPECTION. SELLER will inspect all goods prior to shipment and such inspection will be adequate to meet SELLER’S standards for dimensional and visual characteristics. If BUYER wishes to independently inspect goods prior to shipment, all costs of doing so shall be incurred by BUYER.
      a. Notification to SELLER: BUYER will be deemed to have inspected and accepted any shipment under this contract if, within thirty (30) days after BUYER’S receipt of goods, BUYER has not notified SELLER in writing that such goods are rejected, including a detailed description of the grounds therefore.
      b. Return of Goods: No goods may be returned by BUYER for any reason without SELLER’S prior written approval.
8.   MODIFICATIONS OF CONTRACT: It is agreed that there is no other contract in force between BUYER and SELLER and no alterations, amendments or modifications to this agreement shall be binding unless agreed to in writing by SELLER. Should SELLER by any words, acts or writing, waive or be deemed to have waived any of the provisions of this agreement, or should SELLER fail to insist upon performance by BUYER of one or more of the terms herein, such action or failure on SELLER’S part will in no way be deemed to imply or otherwise constitute a waiver of any other terms contained in this agreement.
9.   SPECIAL DAMAGES AND LIMITATION OF LIABILITY. Under no circumstances shall BUYER or SELLER be liable for any claims for special, indirect or consequential damages relating to or arising from the sale, use or other handling of goods hereunder.
10.   DISCREPANCIES. If BUYER believes there are or may be any errors, omissions or inconsistencies in the Sales Order Acknowledgement, Invoice, or other documents related or supplemental to its order, BUYER must submit a claim, with satisfactory evidence in support thereof, within sixty (60) days of the date of sale.
11.   COLLECTION COSTS. BUYER agrees to pay reasonable attorney fees and legal costs incurred should it become necessary to use such methods to collect any amounts past due. A monthly finance charge of 1.5% (18% annually) may be imposed on any portion of BUYER’S account not paid within the terms stated on the SELLER’S invoice.


Gasket Styles
LB = LineBacker®
GL = Garlock

Type “E” Gaskets
Type “E” Gaskets extend to the outside diameter of the flange. They feature precision located bolt holes, to automatically center the gasket, and offer maximum protection against foreign material “shorting-out” the flange.

Sleeves & Washers
SW = Single Washers
DW = Double Washers
Type Flange
W = Weld Neck
S = Slip-on
O = Other - Denote Specs. and Table

Type “F” Gaskets
Type “F” Gaskets are made to fit within the bolt hole circle of the flange. The O.D. of the gasket extends out to the I.D. of the bolt hole circle for good protection against foreign material “shorting-out” the flange.

For pipe diameters over 24” or ANSI Class pressure ratings of 600# or greater, use G-10 sleeves and G-10 washers where temperatures and other conditions permit.
