It provides a leak-resistant, metal-to-metal seal rated to 3500 psi maximum working pressure. The fitting measures 1.52 inches in overall length and is manufactured from brass meeting ASME-SB75 and ASTM-B75 material standards. It is suited for hydraulic, pneumatic, and instrumentation tubing systems where a secure union connection is required. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers of this fitting in both industrial and commercial applications.\u003c\/p\u003e\u003cp\u003eThis compression union is used wherever two tube runs must be joined without welding or flaring. Common install scenarios include instrument tubing panels, process lines, and hydraulic manifold assemblies in commercial and industrial facilities. The compression x compression end configuration allows connection from both sides using standard compression ferrules. At 0.06 pounds, the fitting is lightweight and suited for confined-space tubing runs where a compact union is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3500 psi maximum working pressure for demanding pressure service\u003c\/li\u003e\n\u003cli\u003eCompression x compression end connections on both sides for tool-assisted, leak-resistant seating\u003c\/li\u003e\n\u003cli\u003eBrass construction conforming to ASME-SB75 and ASTM-B75 material standards\u003c\/li\u003e\n\u003cli\u003e1.52-inch overall length for compact inline installation\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.06 pounds, suitable for panel and rack-mounted tubing assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression tube union for instrumentation, hydraulic, and process tubing systems using standard compression-style fittings.

Depressurize and isolate the tubing system completely before disassembling any fitting. Use appropriate tube wrenches to seat compression ferrules without over-tightening, which can deform ferrules and compromise the seal. Follow applicable ASME and facility piping codes when installing fittings in pressurized systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3500 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.52 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME-SB75, ASTM-B75\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4-2 HBZ-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541785248050,"sku":"4-2 HBZ-B","price":22.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49cdfe2e1a6b7ae0e43a4655cdb0e3b5_87225899-af33-4f1d-ab43-73f5d77a0fc1.jpg?v=1785884853","url":"https:\/\/voomisupply.com\/products\/parker-4-2-hbz-b-compression-tube-union-brass-3500-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
