R-LOK supplies two families in 316 stainless steel. The SQC instrument range covers 1\/8 in to 1\/2 in tube and NPT ports by push-pull, rated 3,000 psig (206 bar) at 70 \u00b0F. The SFQC full-flow range uses a ball-lock sleeve and reaches 6,000 psig (413 bar).<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"\/index.php\/contact\/\">Request a quote<\/a><\/div>\n\n<div class=\"wp-block-button is-style-outline\"><a class=\"wp-block-button__link wp-element-button\" href=\"\/index.php\/products\/\">Browse products<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group rlok-body has-global-padding is-layout-constrained wp-container-core-group-is-layout-b8954cbe wp-block-group-is-layout-constrained\" style=\"border-radius:0px\">\n<p class=\"wp-block-paragraph\"><span class=\"rlok-fallback-nav\"><a href=\"\/index.php\/products\/\">Products<\/a> &nbsp;&middot;&nbsp; <a href=\"\/index.php\/applications\/\">Applications<\/a> &nbsp;&middot;&nbsp; <a href=\"\/index.php\/quality\/\">Quality<\/a> &nbsp;&middot;&nbsp; <a href=\"\/index.php\/resources\/\">Resources<\/a> &nbsp;&middot;&nbsp; <a href=\"\/index.php\/about\/\">About<\/a> &nbsp;&middot;&nbsp; <a href=\"\/index.php\/contact\/\">Contact<\/a><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span class=\"rlok-bc\"><a href=\"\/index.php\/\">Home<\/a> &rsaquo; <a href=\"\/index.php\/products\/\">Products<\/a> &rsaquo; <a href=\"\/index.php\/products\/fluid-control-accessories\/\">Fluid Control<\/a> &rsaquo; <strong>Quick Connectors<\/strong><\/span><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-6ac5c474 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\">Key features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>SQC connectors to 3,000 psig (206 bar); SFQC to 6,000 psig (413 bar).<\/li>\n\n<li>SQC connects by push-pull; SFQC uses a ball-lock sleeve on tube to 1 in.<\/li>\n\n<li>SQC comes with or without an integral shut-off valve; spillage 0.3 to 3.0 cm\u00b3.<\/li>\n\n<li>316 stainless steel wetted parts with Viton (FKM) O-rings; brass SFQC catalogued.<\/li>\n\n<li>Tube ends from 1\/8 in to 1 in, plus 6 mm to 25 mm.<\/li>\n\n<li>SFQC full-flow bore gives Cv to 45.0 with no orifice inside.<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Parameter<\/th><th>Value<\/th><\/tr><\/thead><tbody><tr><td>Series<\/td><td>SQC1, SQC2, SQC3 (instrument) and SFQC2 to SFQC5 (full flow)<\/td><\/tr><tr><td>Body, stem and seal<\/td><td>316 SS with Viton (FKM) O-ring; brass SFQC with NBR<\/td><\/tr><tr><td>Tube ends<\/td><td>SQC 1\/8 in to 1\/2 in, SFQC 1\/4 in to 1 in, 6-25 mm<\/td><\/tr><tr><td>Threads<\/td><td>NPT 2N to 16N, BSPT 2R to 16R, BSPP 4G to 16G<\/td><\/tr><tr><td>Pressure at 70 \u00b0F<\/td><td>SQC 3,000\/1,500\/750, SFQC 6,000\/4,000\/2,000 psig (206\/103\/51.6, 413\/275\/137 bar)<\/td><\/tr><tr><td>Pressure at 400 \u00b0F<\/td><td>250 psig (17.2 bar) for SQC1, SQC2 and SQC3<\/td><\/tr><tr><td>Flow and spillage<\/td><td>SQC 4\/6\/10 US gal\/min (15\/22\/37 L\/min), spillage 0.3\/1.0\/3.0 cm\u00b3<\/td><\/tr><tr><td>Cv and diameter<\/td><td>Cv 0.2 to 3.3 SQC, 1.7 to 45.0 SFQC; body 23.1\/26.2\/30.7 mm<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Instrument and full-flow families<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The SQC series suits instrument lines where a small, light coupling matters more than flow. SQC sizes are SQC1, SQC2 and SQC3, for 1\/8 in to 1\/2 in tube and 1\/4 in to 1\/2 in NPT. Cv is 0.2 to 3.3.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SFQC suits lines that must not be throttled by the coupling. A ball-lock sleeve holds the halves together. Cv reaches 45.0 on the 1 in SFQC5, 26.0 on the 3\/4 in SFQC4. Four sizes cover 1\/4 in to 1 in tube.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Shut-off, spillage and air inclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SQC bodies and stems come in two versions. SO has no valve, so the line is open when the halves are coupled. DO has a shut-off valve that closes on disconnection; Cv on an SQC2P stem falls from 1.5 to 0.5. SFQC has no valve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Catalogue figures for liquid spillage on disconnection and air inclusion on reconnection are equal for each size: 0.3 cm\u00b3 SQC1, 1.0 cm\u00b3 SQC2, 3.0 cm\u00b3 SQC3. Those numbers matter on analyser and sampling lines where the fluid is expensive or hazardous.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Materials, pressures, ends and codes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SQC wetted parts are 316 stainless steel with Viton (FKM) O-rings; SFQC also comes in brass with an NBR O-ring. At 70 \u00b0F, SQC is rated 3,000 psig (206 bar) SQC1, 1,500 psig (103 bar) SQC2, 750 psig (51.6 bar) SQC3.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">End styles: S ferrule tube adapter, M male pipe thread, F female pipe thread. NPT is standard; BSPT and BSPP ends carry separate codes. An SQC2P-S6-DO-SS stem takes a 3\/8 in ferrule tube end with a shut-off valve in 316 stainless steel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Standards referenced:<\/strong> 316 SS barstock to ASTM A479 \/ A276; 304 SS spring wire to ASTM A313; NPT threads per ASME B1.20.1; BSPT per ISO 7-1, BSPP per ISO 228-1; Catalogue working pressures are not ASME B31.3 design ratings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Typical duties:<\/strong> Analyser and process sampling systems;

Material certificates and dimensional inspection reports come with the shipment when they are requested in the purchase order, and every shipment is confirmed in writing before it leaves Changsha.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Should I order the SO or the DO version?<\/summary>\n<p class=\"wp-block-paragraph\">Choose SO when a valve elsewhere already isolates the line and you want the highest Cv; an SQC2P stem gives 1.5 in SO against 0.5 in DO. Choose DO when the upstream half must seal on disconnection, at a cylinder or sampling bottle.<\/p>\n<\/details>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull rlok-cta has-global-padding is-layout-constrained wp-container-core-group-is-layout-c4390f02 wp-block-group-is-layout-constrained\" style=\"border-radius:0px\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-b097105c wp-block-group-is-layout-constrained\" style=\"border-radius:0px\">\n<h2 class=\"wp-block-heading\">Request a quote or technical clarification<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Send us the model, size, material and quantity you need &mdash; or a photo of the existing part.
