Non-corrosive, resistant to water and mild chemicals.<\/li>\n<li><strong>Refor\u00e7o:<\/strong> Multi-plies of high-strength synthetic fiber with helix steel wire. This Wire Braided Hose construction provides excellent kink resistance and vacuum retention. Unlike simple Wire Braided Hose designs, the helix wire adds collapse resistance under suction.<\/li>\n<li><strong>Capa:<\/strong> Black corrugated or wrapped cloth impression SBR rubber. Highly resistant to abrasion, ozone, and weather.<\/li>\n<\/ul>\n<h3>Why Helix Steel Wire Reinforcement?<\/h3>\n<p>The helix steel wire acts as a rigid to prevent the hose from collapsing under full vacuum (0.8 bar). In standard Wire Braided Hose without helix wire, suction can flatten the tube. Our engineering solution uses a helix angle optimized to balance flexibility with crush resistance.<\/p>\n<h3>Safety Factor &amp; Pulse Data<\/h3>\n<ul>\n<li><strong>Safety Standard:<\/strong> 4:1 design factor (burst = 4 x working pressure) per international standard.<\/li>\n<li><strong>Pulse Test:<\/strong> Successfully passed 200,000 impulse cycles at 133% working pressure per ISO 6803.<\/li>\n<li><strong>Vacuum Integrity:<\/strong> Maintains round cross-section at 0.8 bar full vacuum for 10,000 cycles.<\/li>\n<\/ul>\n<h3>Media Compatibility<\/h3>\n<div class=\"ds-scroll-area\">\n<table>\n<thead>\n<tr>\n<th>Fluid Type<\/th>\n<th>Compatibility<\/th>\n<th>Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Water (fresh\/salty)<\/td>\n<td>Excelente<\/td>\n<td>Ideal for dewatering<\/td>\n<\/tr>\n<tr>\n<td>Muddy water \/ Slurry<\/td>\n<td>Good<\/td>\n<td>Flush after use<\/td>\n<\/tr>\n<tr>\n<td>Diesel \/ Fuel<\/td>\n<td>Fair<\/td>\n<td>Not for continuous fuel immersion<\/td>\n<\/tr>\n<tr>\n<td>Mild chemicals<\/td>\n<td>Consult factory<\/td>\n<td>Limit temperature to 60\u00b0C<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Application Industries<\/h2>\n<p>This Fuel Suction &amp; Discharge Hose 300psi is the preferred choice for:<\/p>\n<ul>\n<li><strong>Constru\u00e7\u00e3o:<\/strong> Jobsite dewatering, trench drainage, concrete pump suction lines.<\/li>\n<li><strong>Mining:<\/strong> Pit dewatering, slurry transfer, tailings lines.<\/li>\n<li><strong>Heavy Industry:<\/strong> Plant cooling water, non-corrosive chemical transfer, tank truck loading\/unloading.<\/li>\n<li><strong>Agriculture:<\/strong> Irrigation suction, liquid manure transfer, pond dredging.<\/li>\n<li><strong>Marine:<\/strong> Bilge pumping, deck washdown, ballast water transfer.<\/li>\n<\/ul>\n<h3>Precise Selection Professional Guide<\/h3>\n<h4>Hose Assembly Solutions<\/h4>\n<p>We provide complete hose assembly services using crimped fittings or reusable fittings.

Use protective sleeves at abrasion points.<\/li>\n<li><strong>Bend Radius:<\/strong> Minimum bend radius = 10 x OD. Avoid kinking near fittings.<\/li>\n<li><strong>Suction Use:<\/strong> Keep hose fully immersed or use foot valve. Pre-wet to reduce initial suction resistance.<\/li>\n<li><strong>Fitting Attachment:<\/strong> Use only crimped fittings or reusable fittings rated for helix wire hose. Standard Wire Braided Hose fittings may not seal properly.<\/li>\n<li><strong>Storage:<\/strong> Store below +40\u00b0C away from ozone (motors, transformers). Use guards to protect end fittings.<\/li>\n<li><strong>Inspection:<\/strong> Before each use, check cover for cuts exposing reinforcement. Replace immediately if helix wire visible.<\/li>\n<\/ol>\n<h2>Frequently Asked Questions (FAQ)<\/h2>\n<p><strong>Q1: Can this Fuel Suction &amp; Discharge Hose 300psi be used for diesel transfer?<\/strong><br \/>\nA: Yes, for intermittent diesel transfer (e.g., tank truck loading).
