LLR Partners Inc., the $1.4 billion Philadelphia private equity firm run by Seth Lehr, Howard Ross and their partners as a key province in  Ira Lubert's investment empire, has acquired Singer Equities Inc., Bethesda, www.singerequities.com, which makes rubber hoses, belts, fittings and gasket blanks.
  LLR won't say what it paid Paul Singer and his family for the group. LLR and its managers raised the equity; Sovereign Bank's Robert Mindick arranged the debt, backed by Commerce Bank.

  That includes R/W Connection www.rwconnection.com, Landisville, Pa; Allied Rubber and Rigging www.alliedrubber.com, Butler, Pa.;  Hampton Rubber Co. www.hamptonrubber.com, Norfolk, Va.; National Hose and Accessory www.nationalhose.com, Pasadena, Tx.; and PRC Industrial Supply www.prcindustrial.com, Portland, Me.
