Re: [aus-soaring] Pneumatic couplers

Roger is correct although I found Winter (finer thread) ones were better than PZL (course thread) as would often leak.  For about 10 years Winter now make (or market) 5 way connector and they look better quality but like anything german are expensive and I would have same in stock Ian McPhee Box 657  Byron Bay  NSW  2481  Australia Tel  (02) 66 847 642  Int +61 2 66 847 642 Mob 0428 847 642   Int +61 428 847 642 [EMAIL PROTECTED] www.mrsoaring.com     -----Original Message----- From: Roger Druce <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Date: Monday, 8 April 2002 6:40 Subject: [aus-soaring] Pneumatic couplers There was a 4 way pneumatic connector available (from Winter?) which one found around in gliding years back, ie. 1970's, probably because we all flew Libelle's then.  Ultimately the outer plastic securing ring would break, ie. they were not secure.  It was necessary to make a brass or similar material threaded ring to replace it, and this enabled one to do the connector up tight.  Then one found after time that the 'O' rings might get tired.  Before that time one usually encountered instances of failure by some person to tighten the ring up sufficient to avoid cross flow between the lines, which was a very unsatisfactory result.   So in the early nineties I sourced a five way pneumatic connector from FESTO, a recognised industrial company manufacturing pneumatic equipment and pneumatic controls.  I then lent it to someone rather than accumulate experience with it myself which I could report on!   Nevertheless the FESTO part numbers to make up one connector are:     Qty    Product No.    Description            Price (base, ex tax., 1994)     5 of    208380            KDV-PK-4            2.00 each                                     Terminal socket     1 of    7562                KDVF-5                34.50                                     Multiple coupling     1 of    7557                KSV-5                  30.70                                     Multiple coupling     5 of    7216                KSV-PK-4            3.50 each                                     Terminal plug   This may help some?
