      Important – Read Carefully

      Anhydrous Ammonia (NH3) hose has a limited life and the user must be alert to signs of impending failure. Periodic inspection and testing, as described in the Association for Rubber Products Manufacturers (ARPM) publication: IP-11-2, Anhydrous Ammonia Hose Manual for Maintenance, Testing, and Inspection, is recommended to detect signs indicating hose deterioration or loss of performance before conditions leading to malfunction or failure are reached.

      All new hose assemblies should be inspected prior to use to determine if they have been damaged in storage or shipment. Hose subjected to severe usage - for example, dragged over sharp rock surfaces, or sharply bent in storage or continually exposed to weather - will deteriorate more rapidly than carefully handled hose. The hose should be visually inspected each day before use.

      WARNING: A failure in service can result in injury to personnel or damage to property. Do not use at temperatures or pressures above those recommended by Parker . Anhydrous ammonia is extremely volatile - and poisonous - in both liquid and gaseous (vapor) states. Contact with either state of anhydrous ammonia will burn skin, and is especially damaging to the eyes and lungs. Improper hose applications or failure to inspect the hose may lead to life-threatening situations - poisonous gas leakages, fires, or explosions. Do not use anhydrous ammonia hose for LP gas, natural gas or refrigeration applications. Do not use with male swivel couplings. Do not use LP gas hose for anhydrous ammonia applications. Assemblies are available with stainless steel or nylon reinforcement and come with 2 male x male crimp-on fittings.

      Note: Warranty on bulk anhydrous ammonia hose is valid ONLY when coupled by a Parker certified coupler, using Parker specified couplings.

      Inspection Procedure

      Lay out the full length of the hose in a clean and preferably dry area. Inspect the outside cover of the hose for blistering, excessive abrasion or cuts, and coupling slippage. This inspection should be made when the hose is not under pressure.

      1. Cuts in hose cover, which expose or damage the reinforcement are cause for immediate replacement.  Small cuts, nicks, or gouges in the cover which do not go completely through the cover are not cause for replacement of the hose. Hose strength is controlled by the plies of reinforcement, and for this reason, damage in this area cannot be tolerated.
        Note: Pricking the hose cover is necessary for satisfactory hose performance. A uniformly pricked cover should not be viewed with alarm.
      2. Damage to the textile or wire braid is cause for immediate hose replacement. Wire braid reinforced hose that has been kinked or flattened, so as to permanently deform the wire braid in the depressurized state, should be removed from service.
      3. Blistering or loose outer cover is cause for immediate hose replacement.
      4. Examine couplings for slippage. Only permanently attached fittings are to be used with anhydrous ammonia hose. Bolt on or clamp on type fittings must not be used. Slippage is evidenced by the misalignment of the hose and coupling and/or the scored or exposed area where slippage has occurred. Any evidence of slippage is cause for immediate hose replacement.

      Parker Anhydrous Ammonia Hose Warranty

      Anhydrous Ammonia Hose (Series 7261/7262)

      The Parker Hannifin Industrial Hose Division guarantees each length of Parker Anhydrous Ammonia Hose to be free from defects in material and workmanship for the following periods from date of sale to the end user. No claims under Parker’s warranty will be allowed unless they have been first submitted to Parker for review by our authorized distributor. If, in Parker’s judgment, a defect in material or workmanship does occur, we will replace the hose and couplings on a non-pro-rated basis for the first three years. During the next 4 years, credit will be issued on the following pro-rated schedule:

      Time Period

      Series 7261
      (stainless)

      Series 7262
      (nylon)

      0-36 months 100% 100%
      37-48 months 60% 50%
      49-60 months 50% 40%
      69-72 months 40% 30%
      73-84 months 30% 0%

      All adjustments will be based on the original purchase price.

      This guarantee applies to hose in service and used by original customer (end user) only. It does not extend to any PARKER ANHYDROUS HOSE which has not complied with the latest revision of the Parker Safety Guide (Parker Publication No.4400-B.1); Parker Catalog 4800, Section Safety and Technical Guid, Anyhdrous Ammonia Hose (NH3) Hose; or hose that has been subjected to misuse, neglect, accident, puncturing, or cutting caused by poorly maintained equipment, or malfunctioning reels, guides, pumps, or improper installations.

      THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES EXPRESSED OR IMPLIED INCLUDING THE WARRANTY OF MERCHANT-ABILITY OR FITNESS FOR A PARTICULAR PURPOSE AND NO REPRESENTATIVE OR PERSON IS AUTHORIZED TO ASSUME ANY OTHER LIABILITY IN CONNECTION WITH THE SALES OF PARKER ANHYDROUS AMMONIA HOSE. IN NO EVENT SHALL PARKER BE RESPONSIBLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, AND PARKER’S LIABILITY UNDER ANY CLAIM IS LIMITED TO THE ORIGINAL COST OF THE HOSE AND COUPLING(S), EVEN IF PARKER HAS BEEN PROVIDED WITH NOTICE OF A POTENTIAL LOSS.
